Experimental Study on High Strength Concrete with partial replacement of fine aggregate using polypropylene steel fiber

Abstract

The present study is to investigates changes polypropylene used with various percentages such as 0%,0.5%,1%,1.5%,2%,2.5% in M25 grade of concrete. In this investigation, OPC 53 grade cement, fine and coarse aggregates were utilized. Further, the characteristics of each construction materials and polypropylene properties were determined under the laboratory tests. Afterwards, the specimens were constructed as per Indian standards then sent for seven days, fourteen days, and twenty-eight days curing, then the specimens were tested under the Tension, compression and flexural strength test. The attained maximum compression strength, tensile strength and flexural strength were 22.15N/mm2,3.81N/mm2,5.2 N/mm2, respectively. Finally, these highest strengths of polypropylene concrete, were achieved by 2.5% polypropylene used in concrete.
