Fatigue Property of Concrete With and Without Mineral Admixtures

A number of studies have shown that concrete fatigue strength is significantly influenced by a large number of variables including stress range, rate of loading, load history, stress reversal, rest period, stress gradient, material properties, etc. Effects of these parameters on fatigue characteristics of concrete are addressed in this paper. In general, endurance or fatigue flexural limit of plain concrete was found to vary between approximately 50 and 70% of its static flexural strength. But it can be lower than 50% when concrete is tested in water.
