适当湿润的粉煤灰和贮留池内粉煤灰在混凝土中的应用研究

Application of fly-ash with adequate damping and from storage pond to concrete

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]。

Compared with Portland cement, the different reactions of coal fly - ash were characterized by ： burning （ usually occur in existence of water and lime existing） , speed （ usually slower） . reaction cycle （ generally longer）. Under the condition of damping fly ash can be used for cement component without any effect on the properties of concrete. This paper discusses the changes in properties of concrete when the damped fly ash is used for the component of cement to produce concrete.
