激发剂对蒸养水泥-粉煤灰胶凝材料性能的影响

Effects of Activator on the Hydration Characteristics of Steam Curing Cement Pastes Containing Fly Ash

通过测定不同龄期净浆化学结合水量和抗压强度,并结合SEM,研究了在蒸养条件下激发剂对水泥-粉煤灰复合胶凝材料水化性能的影响。结果表明:蒸养条件及激发剂提高了水泥-粉煤灰复合胶凝材料的水化速度与粉煤灰的活性。

By testing chemically combined water and compressive strength of hardened pastes at different ages and SEM, the influence of activator on hydration characteristics of cement-fly ash composite binders in steam curing condition was studied. The experimental results indicate that the steam curing condition increases the hydration velocity of cement fly ash composite binders and activation of fly ash;
