Effect of Polypropylene Fiber on Mechanical Properties of Concrete Containing Fly Ash

Abstract:

A designed experimental study has been conducted to investigate the effect of the fiber fraction of polypropylene fiber on the mechanical properties of concrete containing fly ash, a large number of experiments have been carried out in this study. The mechanical properties include compressive strength, splitting tensile strength and compressive modulus of elasticity. On the basis of the experimental results of the specimens of six sets of mix proportions, the mechanism of action of polypropylene fiber on these mechanical properties has been analyzed in details. The results indicate that there is a tendency of increase in the compressive strength and splitting tensile strength, and the modulus of elasticity of concrete containing fly ash decrease gradually with the increase of fiber volume fraction with appropriate content.
