Abstract
The effect of different water absorption and texture of fine aggregate on properties of dam concrete is significant. This paper studies the properties of dam concrete made by the same and different kinds of fine aggregates. The results showed that concrete made by fine aggregate with high water absorption have higher degree of hydration, larger workability, lower ultimate tensile strength, compared to concrete made by limestone sand. Concrete made by basalt sand have lower strength, higher dry shrinkage, lower autogenously volume deformation.
