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.
