Strength Of Durability Properties Of Concrete Using Recron 3s

Fiber Reinforced Concrete (FRC) is a composite material consisting of cement based matrix with an ordered or random distribution of fibers that exhibits a synergistic response. In this paper, an experimental investigation on strength of concrete by addition of recron 3s fibers at a dosage of 0-1% by weight of cement has been carried out. Recron 3s acts as "secondary reinforcement" in concrete which arrests shrinkage cracks resistance to impact/abrasion & greatly improves quality of construction. The studies were conducted on M30 mix and tests have been carried out. The compressive strength, split tensile strength, flexural strength, capillary and porosity test of concrete sample was determined and the dosage of fiber varies from 0%, 0.2%, 0.4%, 0.6%, 0.8% and 1%. Finally, the results were compared with the conventional concrete. Keywords— synergistic, Recron 3s fibers, secondary reinforcement, capillary , porosity.
