Strength Prediction of Polypropylene Fiber Reinforced Concrete

Abstract

The main purpose of this investigation is to study the effects of polypropylene fiber on the compressive and flexural strength of normal weight concrete. Four mixes used polypropylene fiber weight with 0.4, 0.8, 1.0 and 1.5% of cement content. To provide a basis for comparison, reference specimens were cast without polypropylene fiber. The test results showed that the increase of mechanical properties (compressive and flexural strength) resulting from added of polypropylene fiber was relatively high. The increase was about 64 percent for compressive strength, while, in flexural strength was about 55.5 percent.
