我国利用粉煤灰的主要部门是建材行业,1979年建材部门利用粉煤灰240万吨,占总利用量的86％;1980年利用310万吨,占总利用量的85％;1981年利用407万吨,占总利用量的82％。除建材部门外,农业改良土壤,填坑平地也用了一部分。其它工业部门用量甚少。建材部门于50年代末期开始对粉煤灰的利用进行实验研究,60年代初期开始建厂,目前几种主要粉煤灰建材产品的企业数、生产能力和实际产量情况见表1: China’s main use of fly ash is the building materials industry. In 1979, the building materials sector used 2.4 million tons of fly ash, accounting for 86% of the total utilization; in 1980, it used 3.1 million tons, accounting for 85% of the total utilization; it was used in 1981. 407 million tons, accounting for 82% of the total utilization. In addition to the building materials sector, agriculture also used soil as a part of the landfill. Other industrial sectors use very little. In the late 1950s, the building materials sector began to conduct experimental research on the use of fly ash, and began construction in the early 1960s. At present, the number, production capacity, and actual production of several major fly ash building materials products are shown in Table 1:
