Critically explore the risks, challenges and key issues in relation to Essay - 2
Critically explore the risks, challenges and key issues in relation to starting up a new restaurant in Cardiff Bay in light of the current economic climate in the UK 01312 - Essay Example Full and quick services restaurant growth for 2015 is forecasted up to 3.4% and 3.7% respectively (Technonic, 2014). The industry value in UK economy with around 35,032 business, 590,915 employees and value of à £26.7billion in 2014 (IBIS World, 2014 and Department of Environment Food and Rural Affairs, 2014). The industry also witnessed an increase in distribution index on an average 1.3% with 4.7% increased outcome for 2014 (Office of National Statistics, 2014 and Office of National Statistics, 2015). The development of worldââ¬â¢s deprived regions has widely captured the attention of opportunists for being early starters in the new markets via filling the spotted gap. One of such regions emerging regions offering fair opportunities is Cardiff Bay. The mining valley holds the status of worldââ¬â¢ first industrialized city (Cardiff Caerdydd, N.d).The last two decades history of the region is adventurously full of growth events and developments. A forecasted population growth and heavily changed lifestyle are promising measures for services business industry (Cardiff Caerdydd, N.d). Ranked as the 10th largest UK city, Cardiff Bay attracts around 18 million visitors a year till 2012. From 1000 registered buildings, 547 are of food businesses including bar, cafà © and restaurants in Cardiff Bay (Ruddick, 2012).Though, the region still needs huge reforms and administrative facilities but critics show positivity towards success of the growing entity. A new sole-proprietorship entity has developed a business plan for entering the Cardiff-Bay restaurant industry to capture opportunities. The plan is apparently developed but lacks the description of risks and challenges associated with the external environmental factors. It is agreed upon a fact, that developing an effective business plan is as challenging and attention seeking as the running a business (Mullins, 2012 and Chesbrough, 2012). Hence, below presented report is a

How a management consultant identifies a potential client Essay
How a management consultant identifies a potential client - Essay Example Management consulting may involve the identification and cross-fertilization of best practices, analytical techniques, change management and coaching skills, technology implementations, strategy development or even the simple advantage of an outsider's perspective. It generally brings formal frameworks or methodologies to identify problems or suggest more effective or efficient ways of performing business tasks. "Management consultants are primarily concerned with initiating and implementing technological, organisational and behavioural changes. Their work involves providing objective appraisals where it is often easier for an expert outsider to see the broader picture and reorganise the long-term requirements of an organisation." In management consultant, identifying a potential client is a very important aspect. One would consider a business organisation that has not been performing well as a potential client. The organisation should be big enough and ready to pay management consultation fees. Such a business organisation would not decline the service of a management consultant for they would be willing to achieve their organisational goals. If given a management consultation by a potential client, then I would start the consultation work immediately. This would involve a number of approach and steps to follow in order to fully identify the real problem with the firm. When it comes to consultation work itself, it involves a management consultant team which must include senior management as well as employees at all levels. A newly-hired graduate will start in a supporting role in team projects and will be involved in the following activities; Taking Responsibility for Gathering and Collating Data At a start of any management consultation, the necessary data has to be gathered and collated. This is the responsibility of a newly hired graduate in a management consultation firm. He goes to the firm that requires management consultation and gathers all the necessary data and put it together. (www.prospects.ac.uk/links/ManConsult/) Processing Figures to be Presented by Senior Colleagues to the Client's Senior Management The figures to be presented to the client's senior management by the management consultant senior colleagues are processed. This is done to ensure that the client senior management get just only the most essential data as far as management consultation is concerned. (www.prospects.ac.uk/links/ManConsult/) Interviewing Clients and other Individuals It is still the work of a newly hired graduate to interview the clients and other individual to gather more information that might be necessary in management consultation work. This should be done in a tactful manner in order to get the correct feedback and also to ensure the clients and other individuals cooperate to provide the information a newly hired graduate is seeking. (www.prospects.ac.uk/links/ManConsult/) Researching External Sources such as the Internet or other Relevant Databases It is still the responsibility

Philadelphia Healthcare System Assignment Example | Topics and Well Written Essays - 750 words
Philadelphia Healthcare System - Assignment Example The Philadelphia healthcare system can be termed as one the most developed health care system. The hospitals in this area are equipped with more than 300 beds which gives them a capacity of over 300 inpatients. A large number of beds in hospitals indicates that the hospitals in these regions are well equipped with facilities to take good care of inpatients. The capacity of a health care system is a critical factor in any region in a country. A large capacity allows the hospitals to respond to emergency matters and guarantee the patients of quality health in a time of need. The availability of these facilities ensures better health care, lower mortality rate and a healthier public in the country. The high capacity of the medical hospitals in Philadelphia indicates that the hospital has the capacity to take care of the health needs of the society. Also, the availability of this capacity indicates that the health system has enough medical personnel to take care of the health needs of th e society. Judging from this capacity, it is possible to regard Philadelphia as one of the best medical health systems in the United States. The hospital care intensity index is one the ratios that are used to measure the quality of healthcare within a health system. This figure provides the ratio between the number of days that a patient stayed in hospital and the number of times that they received attention from the medical staff within the hospital. In essence, this ratio is a representation of the availability of medical staff which in turn indicates the degree to which a healthcare system is equipped with medical personnel.Ã

Narrative Structure and Binary Oppositions Essay Example for Free
Narrative Structure and Binary Oppositions Essay This essay illustrates the understanding of writing aspects of visual composition because they are grammar of a language. In this image, we get to know good literature and good poetry is more than words and subject matter, art is more than pictures. The Safaricom Company had to choose the sentence structure, the style, and so on can make or break a good story. The designer of this graphic show the way the formal elements are arranged and this can make or break a good picture idea. The use of design principles applied to the visual elements is like visual grammar. In the background of this graphic, the children are playing and happy in school, at the same time it is like learning to read and write the language of vision because it develop you with a style of expressing visual ideas, this also helps you to become visual poets. Looking for the visual effects of design principles does not have to limit an artistââ¬â¢s options because it can focus an experimentation and choice making.. The six visual elements which includes: the color, the line, shape, value or tone, texture, volume or form are all display in this image, first we think of the elements as the basic visual material to this art because it is hard to imagine anything visual without the use of one or more of these elements. While, we think of the principles as was to work with and arrange the elements. See more: what is a narrative essay Colors are seen within the brain, it is the eyes that have the receptors that tell your brain what you are looking at, in the picture color explain a lot about this company. The color green was exploded in the visual element to shows their possession in Kenya and are the safari of Kenya with color used. Secondly, the lines used in the graphic design shows the border guiding the page layout and the design is shows the picture in a book form. The third thing is the shape which enable this design unique, even in the picture lots of shapes are shown to give you a better understanding about what information itââ¬â¢s poetry to the audience. Value or tone are shows who the picture was edited well and contrast at the proper level so suit the eyes of the viewers in Kenya , Safaricom had been there for the nation in it start-up. This was the first GSM Company and they had extended throughout the nation, they had brought lots of programs to the Kenyan people. This image tells how the company is in the front of the Kenyan people and ready to go extra mines for them, in the picture a boy is standing outside of a school fence with smile which means, Safari com company and on the campus there are lots of students and they are playing and dancing which poetry the services that the company Safaricom render to the Kenyan people. In another aspects of this graphic Safaricom company is promoting education programs, for those street kids out there who their parents doesnââ¬â¢t have the hands to sponsor them in school, the gender aspects have to do with promoting sexual gender equal because this have lead to many kids abuse and Safaricom is here in this picture saying ââ¬Å"am here for a chanceâ⬠. All these are just tell us how media are involved 95% in preaching polities. Some of the design principles or design rules are broken by artist for example: Emphasis- says ââ¬Å"Center of interest.â⬠It is about dominance and influence. Most artists put it a bit off center and balance it with some minor themes to maintain our interest. Some artists avoid emphasis on purpose. They want all parts of the work to be equally interesting. Harmony- As in music, complementary layers and/or effects can join to produce a more attractive whole. The composition is complex, but everything appears to fit with everything else. The whole is better than the sum of its parts. Unity- When nothing distracts from the whole, you have unity. Unity without variation can be uninteresting- like driving on a clear day through Western Kansas on the interstate. Unity with diversity generally has more to offer in both art and in life. Of course some very minimal art can be very claiming and at times even very evocative. Even the simple landscape in this artwork has a powerful effect. Opposition- uses contrasting visual concepts. That same background of this Safaricom advertisement ââ¬Å"blue skyâ⬠landscape becomes very dramatic and expressive when a sun builds in the southwest. Principles can grow out of any artistic device that is used to produce an effect on the viewer. Balancing is one of the most important things because it is the consideration of the visual weight and importance in this image looks. It is the way of comparing the right and left side of the composition. The boy outside the fence is essentially symmetrical and the other students in the shade background, both sides are similar in visual weight and almost mirrored. Because symmetrical balance often looks more stiff and formal, sometimes it is called formal balance. Asymmetrical balance is more interesting, in the picture both sides again are similar in visual weight but not mirrored. It is more casual, dynamic, and relaxed feeling so it is often called informal balance. Radial balance is not very common but it is like a daisy image as we see in this picture with everything arranged around a center. Rose windows of cathedrals also use this design system too. Of course Safaricom, even though was the first communication company doesnââ¬â¢t look stiff and formal because we think of fluttering the company as nation number one for freedom and spontaneity. It is a case of subject matter and symbolism overpowering formal design effects. This Safaricom image can have many meanings and feeling beyond its ââ¬Å"radiantâ⬠feeling. People might hate it as telling what they should do with their life and on the other hand, many of us canââ¬â¢t help thinking about this great company Safaricom. The extraordinarily textured painted the company. Since we have contemplated those thickly expressed colors and textures with their luscious painterly surface, every other company we see try to become an aesthetic experience filled with fruitful sensations. Variety is used in this image by elements changes. Repeating a similar shape but changing the size can give variety and unity at the same time. Keeping the same size, but changing the color can also give variety and unity at the same time. In visual composition, there are many ways you can change something while simulate Amorously keeping it the same while the depth is effects, space, projection toward the viewer add interest. Linear perspective in the real word makes things duller and small things brighter, and so on, to make the objects contradict realism. Many artists donââ¬â¢t believe in realism even though they could do it if they wanted to. It seems too boring to them. Realism wouldnââ¬â¢t be art for some artists. The way the image repetition is of the visual elements is, one is the size variation that can be applied to shape, form, etc. Notice how size can affect how close or far something can appear to be from the viewer. Example can be the boy in the close view and the rest of the students in a far view. Which one appears closer? Note how size relationships create depth or space in a composition. Children in first grade can already recognize closer and father based on size even though they wouldnââ¬â¢t typically use their pictures unless they were motivated to do so. Repetition can be used on all of the visual elements. If things are repeated without any Shape they can quickly get boring. However repetition with variation can be both interesting and comfortably familiar. Repetition gives motion. While variation can be used with all of the visual elements. See ââ¬Å"varietyâ⬠above. You can do this with all the elements. Artists do this all the time. Color saturation, sometimes called ââ¬Å"color intensityâ⬠or brightness can also gives a feeling or depth and space. Which of these people are farther away in the image? Most second graders can see this effect when they are asked to look for it. These people create the illusion of depth even though they are all the same size. When we analyze artwork we often start with visual effects. We notice something happening. Then we try to figure out why it happens. Motion isnââ¬â¢t a principle. It is one of those magic effects when a still picture has motion. There are lots of ways to get motion. Motion examples: sometimes it has to do with orientation. A diagonal line is more dynamic than a horizontal or vertical line. Sometimes motion depends on the character of the element itself. A straight line may be less dynamic than a zigzag or a curving line. A blended are may appear to flow Depth is another magic effect. Illusion and magic are two threads of the same cloth. Example of depth; sometimes the illusion of depth has to do with orientation also, if you want a chair person to appear further away, you can place them higher on the picture plane. Sometimes the illusion of depth depends on the character of the element itself. A warm color can appear to project and cool color can appear to recede, other things being equal. A light tone (value) can appear to project and dark tone can appear to recede. We can define semiology or semiotics as the study of signs. We may not realize it, but in fact semiology can be applied to all sorts of human endeavors, including cinema, theatre, dance, architecture, painting, politics, medicine, history, and religion. That is, we use a variety of gestures (signs) in everyday life to convey message to people around us. We should think of messages (or texts) as systems of signs, e.g., lexical, graphic, and so on, which gain their effects via the constant clashes between these systems. For example, the menu we consult in a restaurant has been drawn up with reference to a structure, but this structure can be filled differently, according to time and place, e.g., breakfast or dinner (Barthes, 1964, p.28). The goal of semiological analysis is to identify the principle at work in the message or text, i.e., to determine the rhetoric or the grammar trying together all the elements. We get a sense of how language works as a system (Barthes, 1983, p.58) if we think of language as a pair of axes or two planes of metal activity, the vertical plane being the selective principle (vocabulary) and the horizontal dimension being the combinative principle (sentences0. For example, we might select items (words) from various categories in the vertical (associative) dimension, such as kitten, cat, muggy, tom, puss, mouser, sat, rested, crouched and so on, and link them in the horizontal (combinative) plane to formulate statements like the cat sat on the mat. Motivated signs are iconic signs: they are characterized by a natural relation between signifier and signified. A portrait or a photograph is iconic, in that the signifier represents the appearance of the signified. The faithfulness or the accuracy of the representation-the degree to which the signified is re-presented in the signifiedââ¬âis an inverse measure of how conventionalized it is. A realistic portrait (painting) is highly conventionalized this means that to signify the work relies on our experience of the sort of reality it re-presents. A photograph of a street scene communicates easily because of our familiarity with the reality it re-presents. It is important to recognize that in signs of high motivation, the signified is the determining influence, and in signs of low motivation, convention determines the form of the signifier. Finally, after intruding into this design principles and element used to convey information to the viewer, I will conclude by saying the safarcom GSM Company involve themselves in the life on the Kenyan to protect them but at the sometime media is put in front to shows politics. Safaricom choose this graphic because it explains a lot about the Kenyan cultural society. REFERENCES Barthes, R.

Large classes Essay Example for Free
Large classes Essay When students are in large classes it is very hard for the teacher to give every student individual attention. What can educational authorities do about this? It is quite obvious that when the students are in very large numbers in a class, the teacher canââ¬â¢t pay individual attention. I think as far as students are attentive in the class, teachers attention to individual hardly matters. Not all students in a class need personal attention, because they are smart and grasp the lessons quickly by themselves. However some of the students who are a little weak can surely get personal attention of the teachers. Nevertheless for the teacher to be able to monitor progress of all students of a class, it is necessary that proper student teacher ratio is adhered to. Student-Teacher ratio refers to the number of teachers in a school or university with respect to the number of students who attend the school or university. For example, a student teacher ratio of 10:1 means that there are 10 students for every one teacher available. The term can also be reversed to be teacher-student ratio. If one classroom has a 30:1 ratio and the other has a 10:1 ratio, the school could claim to have a 20:1 ratio overall. But if the ratio is 50:1, the school needs to hire more teachers. In a way 40:1 is the ideal ratio where all students can get proper attention of the teacher. Summarizing, this is the responsibility of the educational authorities to inspect schools and universities periodically to ensure a right student-teacher ratio and in the event of this ratio changing due to greater number of students, educational authorities must strictly advice schools to hire more teachers and maintain appropriate student ââ¬â teacher ratio. This shall help all students get better attention of the teachers if not individual attention.

Materials For Cladding System
Materials For Cladding System The materials for cladding are often chosen for their manufacturing parameters, cost, durability as well as appearance. Examples of the materials are metal cladding and precast concrete cladding. Both of these differ in terms of strength, durability and cost of each material. Metal Cladding The durability of a metal cladding is affected by type of material, exposure of the panel, local environment factors, corrosion protection as well as the details of the cladding itself. When using metal cladding, the lifespan of this system is generally defined in terms of its period from the first use to the first maintenance which is the period for when then material may need to be repainted to maintain its original appearance or the original coating system can no longer protects the metal underneath. Usually, metal cladding suppliers will provide detailed information regarding their product including the durability of the metal cladding itself. The coatings of cladding are also affected by the intensity of the exposure to ultraviolet radiation which means less longevity but for organic coated steels, the period to the first maintenance can be as long as 30 years. The durability of a metal cladding can also be affected by the workmanship related defects during the installation proc ess such as scratching the coating. Since metal cladding began to be used in a range wider than simply industrial buildings, then architectural features for aesthetical value such as curved eaves and corners as well as horizontal profiles have been developed. Texture and colours are mixed to form a more interesting cladding rather than a plain metal cladding but the incorporation of architectural features requires huge care over specifications as well as installations. The most used cladding system for architectural purposes are profiled cladding and composite panels which were often laid horizontally and fixed to vertical sub-frames of the building itself. A curved profile panels are produces from flat profiled sheets, either by creating a series of cross ribs that were then adjusted onto the metal locally. The other method in producing curved profile panels involves stretching the profile to provide a smooth curve without cross ribs like the earlier method but this method is more restricted in the range of curves and radii available to be used. For this curved profiled panels, a more careful setting out is needed compared than the flat profiles but it has the advantage in being stiffer than the flat ones. From this, it is obvious that a curved profiled panels and composite profiled panels are more durable yet stronger compared to flat profiled panels. Besides, this can be used as an advantage for architectural purposes which the world often look for nowadays. Precast Concrete Cladding Precast concrete has now become the architectural cladding material of choice because it has the advantage in terms of aesthetics, durability, low maintenance surface, applied finishes, as well as construction economy. This system often combines the benefits of low maintenance, high durability, excellent fire resistant and even energy efficiency. This combination makes precast concrete cladding an ideal solution for the emphasis of prestige, luxury and aesthetic appeal, especially for high rise offices and residential towers or for economy and durability priority such as in lower rise offices and commercial structures. Brick, marble, tile and granite are of typical finishes used for precast concrete cladding but any other decorative stone can also be applied for more variations. This type of cladding system is one of the most cost effective because it is naturally coloured. The main advantage of precast concrete cladding are in terms of installation, where the installation for this cladding system is swift and rapid; the sized of the panels which are typically sized so that they can span grid to grid, allowing a large area of the applied building to be weathered as quickly as possible. Besides, there are no scaffolding required in the installation of this precast concrete system as all fixings are accessed from the rear end of the panels. Sometimes, for construction that needed to use glazing units and insulation, they can easily be fitted to the precast unit in the factory that made the precast unit itself, thus decreasing the time needed for the work. But, in order to make precast concrete cladding system more cost effective, it is important that panel sizes to be maximized and a degree of repetition exists which these will ensure a number of panels can be casted from a single mould. Two types of sub surface drainage system for domestic usage In building a good drainage system, there are few principles that need to be followed. Some of them are: Material should have adequate strength and durability. Every part of a drain should be accessible for the purpose of inspection and cleansing. Drains should be in straight run as far as possible. Drains must be laid to a gradient which will render them efficient. The fall or gradient should be calculated according to the rate of flow, velocity required, and the diameter of the drain. Every drain inlet should be trapped to prevent the entry of foul air into the building which the minimum seal required is 50mm. For domestic usage, there are three types of subsurface drainage system which are combined system, separate system and partially separate system. The scheme or plan layout of drains will depend upon factors such as number of discharge points, relative position of discharge point, and drainage system of the Local Authority sewers. Combined System In a combined system, all the drains are discharged into a common or combined sewer. It is the most simple and economic method since there is no duplication of drains. This system has the advantage in terms of easy maintenance. Besides, all drains are flushed when it rains and it is impossible for this system to be connected to the wrong sewer. But this system also has its disadvantage, which is that all the discharges should pass through the sewage treatment installation, which might be costly and prove to be difficult with periods of heavy rain. Separate system A separate system in domestic subsoil drainage is the most common method applied by the Local Authorities where two sewers are used in this method. One of the sewers receives the surface water discharged and conveys them direct to a suitable outfall such as a river or sea, where the discharges require no treatment while the second sewer receives all the soil or foul discharges such as from baths, basins, sinks, showers as well as toilets. These discharges will then being conveyed to the sewage treatment installations. In this system, more drains are required and it is often necessary to cross drains one over another. There is a risk of connecting the drain to a wrong sewer and the soil drains are not flushed during heavy rain, but the savings on the treatment of a smaller volume of discharge leads to an overall economy which is acceptable to be applied in domestic area. The function of road and pavement A road is an identifiable route, way or path between two places which might or might not be available for the use by public. Public roads, especially those major roads that connect two destinations are defined as highways. A modern road normally smoothed and paved to allow easy travel of road users. While pavement is defined as surfaces intended for traffic and soil, which are protected by an overlay of imported or treated material with the objective to limit the stress in the ground. The surface of road as well as its associated construction is known as pavement. One of the main functions of roads and pavements is to transfer and distribute transportation load onto the ground. Even on the ground soil itself we can use to travel, but the loads of the transportations that use the path is not evenly distributed since the soil is not compacted and supported. With roads and pavements, the loads of the transportations were equally distributed and this provides a safe and comfy journey. The second function of road and pavement is to provide a flat surface. This is to achieve a comfortable, smooth and safe journey. A smooth riding surface is important for riding comfort and throughout the road development; this has become the measure of how road users see of a road. A rough surfaced road can be caused from few factors; one of it is caused from pavement distress due to structural deformation. Besides, the other major factor of road and pavement is to prevent the subgrade from being damaged. Subgrade is the supporting soil underneath the pavement. It is important to protect the subgrade as it is the foundation for the road and pavement. Like building, if the foundation is damaged, the whole pavement is damaged as well. If the subgrade is over-stressed, it will deform and lose its ability to properly support the loads above it. So, the pavement should have sufficient structural capacity in terms of strength and thickness, to adequately reduce the stress so that the loads and stress do not exceed the strength and capacity of the subgrade. The thickness and strength can vary depending on the combination of subgrade types as well as loading condition. Roads and pavements are also used to provide adequate surface friction or in other words, roads and pavements are to provide a skid resistance surface. The priority in road user requirement is that of safety. Every road user concerns about their safety when using roads. Safety, especially in wet conditions such as during heavy rains, can be linked to a loss of surface friction between the tyre and the pavement surface due to the existence of water surface on the road itself. So it is obvious that roads and pavements should be able to provide an adequate skid resistance for road users, in any weather conditions. The last function of roads and pavements is to provide a waterproof layer. The outer surface of a pavement acts as a waterproof surface which prevents the subgrade that supports the pavement from becoming saturated because of water absorption. When they become saturated, the soil loses its ability to support the applied loads, let alone overload, and this will lead to a premature failure of the pavement itself. So, the outer layer should not contain even a tiny pore, in order to prevent water from being absorbed underneath. Cellular concrete roofing units, pavement overlays, bridge decks airport runways, pressure vessels, blast-resistant structures, tunnel linings and ship-hull construction are some applications of a particular fiber reinforcement concrete. The types of the fibers with characteristics comparison with the conventional concrete. Fiber reinforced concrete can be defined as a composite material which consists of a mixture of cement, mortar or concrete and discontinuous and uniformly dispersed suitable fibers. The addition of this fiber would act as crack arrester as well as improving its static and dynamic properties. Fiber reinforced concrete is used as it has the advantages of static and dynamic tensile strength, energy absorbing characteristics and an improvised fatigue strength. The main factor that affects its properties is the relative fiber matrix stiffness where the modulus of elasticity of matrix helped in stress transfer efficiently. A good bond is important to improve the tensile strength of the material. There are many applications with different types of fibers and these were affected by the characteristics of the certain fiber containing in the concrete: Glass Fiber Reinforced Concrete (GFPC) Glass fiber reinforced concretes are mainly used in exterior building panels or as an architectural precast concrete. One of the advantages of GFPC is that they are lightweight. Despite their light weight, a GFPC panel is strong and is more environmental friendly as they were mostly made of recycled post-consumer glass. Steel Fiber Reinforced Concrete (SFRC) Steel fiber reinforced concrete is a composite material made of hydraulic cements, water, fine and coarse aggregate and a dispersion of small, discontinuous steel fibers. The steel fibers are distributed uniformly throughout the concrete matrix which gives the SFRC the ability to control temperature and shrinkage cracks. They were commonly used in cellular concrete roofing unit. Polypropylene Fiber reinforced Concrete (PFRC) Polypropylene fiber reinforced concrete has the ability to improve freeze-thaw resistance, improve resistance to explosive in case of severe fire, and improves impact resistance. It is often used in foundation piles, pre-stressed piles and facing panels. Asbestos Fiber Reinforced Concrete (AFRC) Asbestos fiber reinforced concrete has been used since early 1900s which were applied into concrete. Unfortunately, this composite became a concern as it is venomous to health but AFRC were still used in some applications which is outside of health zone such as in pipes and sewer pipes. Mica Flakes Fiber Reinforced Concrete (MFRC) This type of fiber reinforced concrete partially replaces asbestos applications in cement boards, concrete pipes and repair materials. Mica flakes as fibers can help preventing long-term decreases in terms of tensile strength as well as impact strength. Carbon Fiber Reinforced Concrete (CFRC) Carbon fiber reinforced concrete is an electric conductor concrete and by this, they are normally used in locations where electrical contacts are necessary. Besides, it has the characteristic of corrosion resistance, compared to other metallic electrical contact materials. Fiber Reinforced Concrete (FRC) Conventional Reinforced Concrete Higher durability Lower durability Protect steel from corrosion Steel prone to corrosion Lighter (in terms of materials) Heavier (in terms of materials) More expensive Economical Greater strength (per 1mÃâà ³) Weaker (per 1mÃâà ³) Higher workability Less workability Table: Characteristic comparison between FRC and conventional concrete The above table shows the characteristic comparisons between fiber reinforced concrete and conventional concrete. in terms of durability, FRC is more durable compared to conventional concrete this is because of the presence of fibers in FRC that adds to the durability of the concrete and thus, making it more flexible to be used widely in construction. Besides, the weight of FRC is relatively lighter compared to conventional concrete. Such as for Glass Fiber Reinforced Concrete, both the glass and concrete make up the volume and thus decreasing the weight as the fiber contained in the concrete has lower mass compared to a full conventional concrete. This superb characteristic increases the workability of the FRC, beating conventional concrete in terms of weight as well as workability. The workability of a FRC will reduce if the fiber volume is increased. Therefore, the volume of fiber need to be controlled but this is an advantage as the cost for materials will not be that high. the workability of FRC can be measured by conducting a Vebe test. Unfortunately, a fiber reinforced concrete is more expensive as it is needed to be readily made in factories, so does the material costs which need to make up for the materials for fiber. But, from the table, it is obvious that FRC has more advantage over conventional concrete, despite the costs. So, this higher cost for sure will increase the reliability of the material, and the building itself.
