大掺量粉煤灰混凝土在生产中的应用

Application of the Concrete Added More Flyash in the Production

简述了粉煤灰在混凝土中的作用机理及在生产中的应用,说明了大掺量混凝土用水量低、水胶比低、泌水率低,是质量优良耐久性好的高性能化混凝土,且具有良好的工作性能和早期抗裂性能。开发大掺量粉煤灰,对促进混凝土技术发展,提高建筑质量,加强环境保护有重要意义。

The paper introduces the action mechanism of flyagh in concrete production and the application. The concrete added more flyash is low on consuming water,water- glue ratio and bleeding rate.It is a kind of high- performance concrete with high quality and better durability, operational performance and crazing resistane at early stage. It is of great importance to developing concrete technology, construction quality and environmental protection.
