Study of performance of steel and polypropylene fiber reinforced concrete

Abstract

In this paper, we studied the performance of fiber reinforced concrete (FRC) with steel and polypropylene fibers. Here M 40 grade of concrete reinforced with different percentage of steel and polypropylene fibers was experimentally investigated for the compressive strength and tensile strength of FRC. The percentage variation of steel fiber is taken as 0.5%, 1.0% and 1.5% by volume of concrete for steel fiber reinforced concrete (SFRC). The percentage variation of polypropylene fiber is taken as 0.1%, 0.2% and 0.3% by volume of concrete for polypropylene fiber reinforced concrete (PPFRC).The practical results obtained has been studied and analyzed by comparing it with a control sample specimen (0% fiber). The relationship of compressive strength, tensile strength vs. percentage of fiber, has been represented graphically. Observations clearly shows the significant improvement in 28 and 45 days compressive strength and tensile strength for M 40 grade of concrete on addition of fibers along with enhanced properties of fiber reinforced concrete.
