Abstract
The focus of this study is to examine flexural fatigue durability of RC beams, which were made with various cementitious materials. The cementitious materials tested in this study were blast furnace slag powder, fly-ash, silica-fume, and an artificial admixture of rich SiO2 and Al2O3. Fifteen RC beams for each admixture were prepared in addition to a control mixture (without admixture). The dimensions of the RC beams without stirrups were 160 x 160 x 1200 mm. Three beams for each mixture were soaked into a water-tank until the cyclic loading test. The study conducted static and cyclic four-points bending test. The paper aims to report the effect of the alternative cementitious materials on the fatigue durability of RC beams, which were exposed to the dry and wet environmental conditions.
