EVALUATION OF THE STRENGTH OF POLYPROPYLENE FIBER REINFORCED CONCRETE WITH ARTIFICIAL & NATURAL SAND

This paper presents the experimental result of Compressive and Tensile Strength of polypropylene fiber in concrete with 40% natural sand and 60% artificial sand.different volume fraction of polypropylene fiber 0., 0.5, 1.0 and 1..5% by weight of cement are used. Concrete mix prepared with 100% Natural sand as a normal mix and also mix with optimum percentage of Natural sand & Artificial sand ie. 40% Natural sand and 60% artificial sand is used. For the purpose of experimentation concrete mixes are designed for M30 grades of concrete.In this program we are going to construct 48 cube samples of size 150mm x150mm x150mm for different percentages of polypropylene fiber with 60% Artificial sand & 40% natural sand. so as to determine the best proportion, which would give maximum compressive strength. It reveals that with 1% polypropylene fiber with natural and artificial sand were found to be most favorable combinations for casting of concrete flexural members.
