Properties and Applications of Fiber Reinforced Concrete- A Review

Abstract
The concepts of using fibres in order to reinforce matrices weak in tension is more than 4500 years old.since Portland cement concrete started to be used widely as a construction material attempts were made to use fibres for arresting cracks enhance the strength etc. The development of fibre reinforcement for concrete was very slow before 1960’s. Fibers are generally used as resistance of cracking and strengthening of concrete. In this project we are going to compare the compressive strength of 3, 7 and 28 days of aramid fibres to the ordinary concrete and fibre reinforced concrete i.e. glass fibres and steel fibres. The concrete is design for M20 grade of concrete. According to various research papers, it has been found that steel fibers give the maximum strength in comparison and glass fibre is used for crack resistance but aramid simultaneously gives strength and can be used for crack resistance. Now a days there exists many reinforcement techniques for improving the strength of those materials which lacks load carrying and less durable capacity. Fiber reinforced concrete has been successfully used in slabs on grade, shotcrete, architectural panels, precast products, offshore structures, structures in seismic regions, thin and thick repairs, crash barriers, footings, hydraulic structures and many other applications. This review study is a trial of giving some highlights for inclusion of aramid fibers especially in terms of using them with new types of concrete. A fiber mix generally requires more vibration to consolidate the mix. External vibration is preferable to prevent fiber segregation. Metal trowels, tube floats, and rotating power floats can be used to finish the surface. Concrete ingredients are firstly collected from various locations. As per IS specification material is tested i.e. test which are usually performed to check the material’s physical properties. The proportioning of quantity of cement, materials like fine aggregate, coarse aggregate and fibres like Glass fibre, Steel fiber and Aramid fibre has been done by weight as per the mix design . Water, super plasticizer were measured by volume. Concrete was design for M20 grade as per IS 4562000 and IS 10262. The mixing process is carried out in concrete mixture.
