Dr. A. Vijayakumar, Revathi K, Manojkumar R

Abstract: Now a day?s fibre reinforced concrete has many applications in concrete and construction industry. In this experimental study an attempt has been made to study the full replacement of fine aggregate by Quarry dust and addition of chemical admixture (SBR Latex) in the concrete to increase the strength. Nylon fibre in percentage of 0.5%, 1% and 1.5% is added to the concrete to overcome the very low tensile strength and resistance to cracking. The compressive strength, spilt tensile strength and flexural strength of conventional concrete and nylon fibre concrete of grade M30 with chemical admixture were studied.
