A REVIEW ON FIBER REINFORCED CONCRETE

Concrete plays a vital role as a construction material in the world. But the use of concrete as a structural material is limited to certain extent by deficiencies like brittleness, poor tensile strength and poor resistance to impact strength, fatigue, low ductility and low durability. In the present scenario, waste materials from various industries and admixtures are added to the mix. Over 300 million tons of industrial wastes are being produced per annum by chemical and agricultural process in India. These materials pose problems of disposal and health hazards. Hypo sludge is the waste material from paper industry that has some chemical properties similar to that of cement. Hence it can be used as an economical building cementitious material thus reducing the disposal and air pollution problems caused by the paper industry. Recron 3s acts as "secondary reinforcement" in concrete which arrests shrinkage cracks resistance to impact/abrasion & greatly improves quality of construction. In this study, an experimental investigation shall be conducted on strength of concrete containing hypo sludge and recron 3s fibers. Hypo sludge has to be added at a dosage of 25%, 50% and recron 3s fibers has to be added at a dosage of 0.5%, 1% by weight of cement. In this paper, studies shall be conducted on M30 mix and tests like compression test, split tensile test, flexural test, capillary and porosity shall be conducted. Finally, the results of fiber reinforced concrete shall be compared with the conventional concrete.
