粉煤灰综合利用的现状及发展趋势

Fly Ash Utilization Technology Research and Development Trends

将粉煤灰变废为宝进行综合利用是现实中急需解决的问题。叙述了粉煤灰的基本性质和组成以及粉煤灰在高性能混凝土、新型胶凝材料和建筑制品、农业生产、环境保护等方面的综合利用状况,提出,中国粉煤灰综合利用发展的建议。

The way of original slag discharging not only pollutes the environment,destroys the soil,but also wastes resources,the loss outweights the gain.therefore reutilized,comprehensive utilization of fly ash,is problems needed to be resolved in reality.This paper introduces the development of fly ash in all aspects,such as fly ash in high performance concrete,new cement materials and building products,agricultural production,environmental protection,etc.In addition,a suggestion of to our country the comprehensive utilization of coal ash is put forward.
