In this study, a series of experiments is carried out to investigate the fatigue charateristics of plain concrete in water and seawater which is subjected to cyclic loading with constant amplitude. A total of 200 cylindrical specimens (ø10x20 cm), which were made by readymixed concrete, are prepared for this study. From these series of tests, it is observed that the static and fatigue compressive strength of plain concrete in water and seawater is consideraly lower than that in air. The fatigue strength of the concrete in water is decreased with comparision to that in seawater when stress ratio(??)is less than 0.1, but the concrete in water and seawater has similar fatigue characteristics when the stress ratio is not less than 0.1. And it has been found that the fatigue strength of the concrete in water and seawater is affected by the stress ratio.
