与硅酸盐水泥相比,煤粉粉煤灰的不同反应特征表现在灼烧(通常在有水和石灰的条件下才会发生)、速度(通常较慢)和反应周期(一般较长)上。粉煤灰在湿润状态下可以用作水泥的组分而不影响混凝土的性质。当然在推广使用湿粉煤灰之前显然还有一些技术和应用问题需要解决。文章就粉煤灰加水后用作水泥成分制备混凝土时性质的变化进行讨论[1]。
The different reaction characteristics of pulverized coal fly ash compared to portland cement are characterized by burning (usually only with water and lime), speed (usually slower) and reaction period (generally longer) on. Fly ash can be used as a component of cement in wet conditions without affecting the properties of the concrete. Of course there are obviously some technical and application issues that need to be resolved before the promotion of wet fly ash. The article discusses the properties of fly ash when used as a cementitious material for the preparation of concrete changes [1].
