Abstract

The preparation of high-strength mortar with super fine sand from waterway engineering and the improvement of its mechanical properties by mineral admixtures were studied in this paper. The effect of fly ash, silica fume and both of them on compressive strength and flexural strength of super fine sand mortar were tested. The result shows that fly ash can reduce the early compressive strength and flexural strength of mortar, but improve the rate of gain in strength. Silica fume can improve the early strength of mortar, but reduce the rate of gain in strength. Fly ash and silica fume admixture can play a complementary role between admixtures. The maximum compressive strength of 28d sample reached 45.6MPa, with the help of fly ash and silica fume together.
