压制低水胶比条件下硅酸盐水泥-粉煤灰体系的水化分析

Hydration of Partland Cement-Fly Ash Composite Binder in Low Water Binder Ratio with Press

在压制低水胶比条件下,研究硅酸盐水泥和粉煤灰复合胶凝材料体系的水化程度和水化速率,并利用SEM和XRD分析了水化产物的微观结构。结果表明,在压制低水胶比条件下,水泥的水化受到限制,掺加粉煤灰后能够改善硅酸盐水泥的水化条件,提高水化程度。

The hydration products and microstructures of hardened pastes of the Partland cement-fly ash composite binder were investigated. The influences of molding press of the sample on the degree of hydration and the hydration velocity were also investigated. The results show that hydration is limited in the low water binder ratio with press and that mixing a proper quantity of fly ash can improve cement hydration environment, and increase degree of hydration.
