Experimental study on behavior of fiber reinforced concrete for rigid pavements

Abstract

This paper deals with experimental investigation on mechanical properties of M 20 grade concrete by incorporating polyester fibers in the mix. Polyester fibers of 0.1%,0.2%,0.3%,0.4% by weight of cement are added to the mix. A comparitive analysis has been carried out for conventional concrete to that of the fiber reinforced in relation to compressive, split tensile, flexural strengths. As the fiber content increases compressive, split tensile and flexural strengths are proportionally increasing. It is observed that 0.3% fibers by weight of cement is the optimum dosage. It is found that with 0.3% fiber content results in 20% reduction of pavement thickness.
