Abstract

Fiber reinforcements have incorporated in concrete mixes to improve the tensile strength and performance of concrete structural elements. In this study, the effect of abaca fibers on improving the tensile and flexural of natural fiber reinforced concrete is investigated through splitting tensile and three-point bending tests. With water to cement ratio held constant at 0.49 and a variation of fiber volume from 0% to 2%, the results showed a optimum fiber addition percentage of 1% weight of cement yielding maximum tensile strength of 2.32 MPa and flexural strength of 4.45 MPa. Increasing the fiber volume up to an optimum percentage results to an increase in strength, but further addition of fibers results to a decrease in strength. Though there was no significant increase in the tensile and flexural strength of the concrete specimens with the addition of fibers, it was observed that the fibers bridge the crack in the concrete after reaching its ultimate load bearing capacity.
