EXPERIMENTAL STUDY ON DUCTILE BEHAVIOUR OF FIBRE REINFORCED CONCRETE

Concrete is a very strong and versatile moldable construction material. It consists of cement, sand and aggregate (e.g., gravel or crushed rock) mixed with water. The cement and water form a paste or gel which coats the sand and aggregate. When the cement has chemically reacted with the water (hydrated), it hardens and binds the whole mix together. The initial hardening reaction usually occurs within a few hours. It takes some weeks for concrete to reach full hardness and strength. Concrete can continue to harden and gain strength over many years. Concrete is the second most widely used substance after water and over six milliard tons of concrete is produced each year. Concrete is specified to different applications like a new construction, repair, rehabilitation and retrofitting. Concrete building components in different sizes and shapes include wall panels, doorsills, beams, pillars and more. Post tensioned slabs are a preferred method for industrial, commercial and residential floor slab construction. It makes sense to classify the uses of concrete on the basis of where and how it is produced, together with its method of application, since these have different requirements and properties The fiber Reinforced concrete is the concrete made with the hydraulic cement, containing fine, coarse aggregate and discontinuous fiber or concrete incorporating relatively short, discrete and discontinuous fibers
