Not only can the reusing of flyash solve the problem about pollution,meanwhile,it also is able to make products by reusing flyash.Based on the analysis of the character of flyash,this paper provides that flyash should be used in construction firstly and wall material producing in priority and other producing such as wall material and sewage disposal gradually.At the same time,the view that this paper provides an deep analysis about it. Key words: flyash、reusing of flyash、construction、wall material、sewage disposal 目 录 中文摘要 1 Abstract 2 第一章 绪论 4 第二章 粉煤灰的综合利用 4 2.1粉煤灰的产生 4 2.1.1粉煤灰的形成 4 2.1.2粉煤灰的排放 5 2.1.3粉煤灰的分类 5 2.2粉煤灰的组成与性质 6 2.2.1粉煤灰的组成 6 2.2.2粉煤灰的物理性质 7 2.2.3粉煤灰的化学性质 7 2.2.4粉煤灰的活性 8 2.3粉煤灰综合利用分析 8 2.3.1用于生产混凝土、水泥、砂浆 8 2.3.2用作土建原料、建材生产 9 2.3.3用作环保材料处理污水 9 第三章粉煤灰用于建筑工程 9 3.1粉煤灰混凝土 9 3.1.1粉煤灰在高性能混凝土中的作用机理 10 3.1.2粉煤灰加气混凝土 11 3.2粉煤灰水泥和粉煤灰砂桨 11 3.2.1粉煤灰水泥 11 3.2.2粉煤灰
