Abstract
Concrete is mainly used material for the construction of various types of structures in the modern time of civil infrastructures. Concrete is strong in compression but it is weak in tension and shear. In modern development of fibre reinforced concrete some new type of fibres like glass, carbon, polypropylene and aramid fibres are provided in plain concrete for the improvement in tensile strength, fatigue characteristics, shrinkage characteristics, impact, flexural strength, and compressive strength. The mechanical properties of fibres reinforced concrete is studied by using (steel fibre, glass fibre and polyamide) with different weight fraction of fibres with respect to cement.
Keywords: Concrete Fibres, Compressive strength, Flexural strength, Mechanical Properties.
1. Introduction
Fibre reinforced …show more content…

The bond can be improved by increasing the surface roughness of fibres, or by increasing the aspect ratio.Therefore, in this study, I have tried to take one additional step to complete the big issue by carrying out the tests with high fibre content (2.0%). The result shows that FRC has maximum strength at 1.5% as compare to 2.25%with little effect on compressive strength but increase tensile strength of concrete matrix (Hamrawy 2007).

2. Methodology:
The experimental scheme comprises tests in compression strength test, flexural strength test and split tensile strength test. For obtaining Compressive strength at 7 and 28 day (39+39) =78 cube specimens of 150x150x150mm size each were Casted. (39+39)=78 cylindrical specimens each with 150mm x 300mm height were casted to find split tensile strength and (39+39)=78 beams prisms of size 100x100x500mm each were cast to find flexural strength.

    STRUCTURE Kevlar Aramid Fiber is a synthetic (man-made) material known as Polymer. A polymer is a chain that is made up of many similar molecular groups, better known as ‘monomers’ that are bonded together. The ‘Monomers’ are made up of fourteen Carbon atoms, two Nitrogen atoms, two Oxygen atoms and ten Hydrogen atoms. A single Kevlar polymer chain could possibly have anywhere from one to five million monomers bonded together. A group of polymer chains can be organised together in a fiber.

    Issues of defective construction or failure of building had been occur since all time ago. Each of the cases of defective construction has their own reason and most of the reason is related to its building. The main causes of the structural failure are not come from the loading but it determine by the defective design of the building. Other than that, the inferior construction material also may be the reason since the loads are being calculated based on the material specification. Usually the failure which comes from material is due to the changes material that difference from the exactly material that should be used in the construction.

    According to major supplies, “Use of synthetic fibers for reinforcing concrete is continuously, increasing. The increase has been considerable since 1980, but slowed somewhat in 1990, a year of substantial construction cutbacks. Apparently the construction community believes there are advantages in the use of synthetic fibers in concrete.” (Schupack) Synthetic fibers are used to improve crack control in concrete. Some reports say that synthetic fiber reinforced concrete (SFRC) would replace welded wire fabric in many slab-on-grade applications. But in reality if the welded wire fabric is placed properly it controls crack width better than the synthetic fiber reinforced concrete. In a case study of the use of synthetic fibers in reinforced concrete, the following conclusions were obtained. No matter what concrete placing job is being done, there is no substitute for good concrete practices. The use of a low fiber volume mix will help control plastic shrinkage cracks and bleeding, but not give good cracking control once the crack forms. The synthetic fibers running through a crack have a poor bond providing no shear friction. Impact and toughness tests on synthetic fiber reinforced concrete imply less edge spalling will occur. The American Concrete Institute (ACI) conducted two studies on polypropylene fiber reinforced concrete, one dealing with plastic shrinkage cracking and the other on permeability characteristics. Plastic shrinkage cracking occurs when the surface water on the concrete evaporates faster than the bleed water reaches the surface of the concrete. It was determined by the plastic shrinking cracking study that polypropylene fibers helped reduce the total plastic shrinkage crack area on test panels. Also determined is that the screeding rate affects the total crack area in polypropylene reinforced concrete, while finishing operations showed no significant effects. This study also suggests the use of longer fibers (about 0.75in.) will produce less crack area. “Permeability plays an important role in long-term durability of concrete materials. Permeability of concrete generally refers to the rate at which particular aggressive substances (water, sulfates, chloride ions, etc.) can flow through the concrete.” (Soroushian) As discussed in the plastic shrinkage study that polypropylene fibers reduce cracking. Less cracking in the concrete surface that surface would be less permeable. In the permeability study, they concentrated on the effects of chloride and the permeability of the concrete. The results of this study concluded polypropylene fibers had little effects on chloride permeability of concrete. The polypropylene fibers only help reduce plastic shrinkage cracks.

    ABSTRACT: This article is a portion of a comprehensive study on carbon fibre reinforced plastics. The thermal behaviour and dynamic and tensile mechanical properties of polypropylene carbon fibres composites are discussed. Carbon Fibre Reinforced Plastic is similar to fibre glass which is woven into a textile material and resin such as epoxy resin is applied and allowed to cure. The resulting material is very strong and has the best strength to weight ratio of all construction materials. It is an improvement on glass fibre-reinforced plastic, although much more expensive. Carbon Fibre Reinforced Polymers tend to be used in the manufacture of expensive sports cars, where strong and light materials are required. Expensive, competition bicycles

  • Alternatives to Concrete

    949 Words  | 2 Pages

    Concrete today is considered by many modern engineers and architects as a more efficient and effective alternative to steel n regards to the creation of buildings, ranging from low-story apartments to neck-breaking skyscrapers. Through the rapid growth and development of the world's major metropolises and growing cities, concrete today has become one of the most important building materials to date. According to the World Business Counsel for Sustainable Development (WBCSD), “it has become the most consumed substance on earth, only superseded by water, with three tons for each person used annually” (World). This huge demand for concrete makes the cement industry one of the world's largest carbon dioxide producers, accounting for about five percent of all man-made pollution. “Approximately one ton of carbon dioxide is put into the atmosphere for every ton of cement used” (World). The cause for this problem is the increase of the global population and the increasing demand for land and energy. It's effect is that as the population continues to increase, it forces builders and developers to meet the quota of creating unlimited amounts of infrastructure within a limited resource-filled world. Knowing this, a proposed and widely agreed solution is to make the concrete in an environmentally-conscious way that will incorporate more demolished concrete, scrap from past projects, and other recycled aggregates.

  • Carbon Fibre Essay

    1806 Words  | 4 Pages

    Carbon-fiber-reinforced-polymer (CFRP) is a composite polymer made up of carbon fibers and a binding polymer. The binding polymer can be a thermoset resin or thermoplastic polymer(s). Examples of thermoplastic polymers that can bind with carbon fiber to make CFRP are polyester, nylon, or vinyl ester. A thermoset resin that can combine with the carbon fiber to make CFRP is epoxy. The combination of the carbon fibers and a thermoset resin or thermoplastic polymer producing CFRP results in a light weight fiber-reinforced plastic that is tremendously strong. Depending on the binding polymer, CFPRs have a wide range of applications and are used when a light weight material with high rigidity and strength are required.

    At the meantime, the push-out technique is considered as a valuable and useful method for evaluating these goals (23). Various factors are involved in the flexural strength of composites. Reducing the size of the filler material followed by increasing the amount of filler material in the composites lead to an increase in the flexural strength of the composite due to better inter-composite stress transfer and improved mechanical properties of the composite (24-26). In addition, the type of filling material is also effective on flexural strength and the high-strength filling material increases the flexural strength of the composite
