    Abstract

    Although many studies have been conducted on the physical properties of superplasticized concrete, very little research has been reported on the fatigue properties of superplasticized concrete. The purpose of this study was to determine the fatigue properties of concretes with superplasticizers and compare these properties with those of concrete without superplasticizers.

    More than 120 concrete specimens at three levels of water/cement ratio, and two levels of cement content, with and without superplasticizers, were subjected to compressive fatigue loading in which the stress varied from essentially zero to a predetermined maximum stress as percentages of the compressive strength.

    For plain concrete, the fatigue strength of superplasticized concrete was not significantly different from that of nonsuperplasticized concrete. Also, water/cement ratio in the range of 0.4 to 0.6 did not appreciably affect the fatigue strength of superplasticized concretes.
