Effect of PVA Fiber on Flexural Properties of High-Performance Concrete

Abstract:

In order to study the effect of the fraction of PVA fiber on the axial compressive strength and flexural properties of high performance concrete, a series of tests have been conducted in this study. The middle span deflection was measured by a micrometer with dial indicator, and six different concrete mixes have been chosen. Flexural properties include flexural strength and flexural modulus of elasticity. The mechanism of PVA fiber acting on axial compressive strength, flexural strength and flexural modulus of elasticity has been analyzed in details. The results indicate that there is a tendency of increase in the axial compressive strength and flexural strength when the fiber volume fraction is below 0.08%, and the flexural modulus of elasticity of high-performance concrete decrease gradually with the increase of fiber volume fraction.
