长期以来,建材行业一直积极致力于粉煤灰的综合利用。据不完全统计,“七五”期间建材行业共利用粉煤灰3000万吨左右,相当于节约灰场建设投资近2亿元,节约土地1.5万亩,节约标煤200万吨左右。1989年建材行业综合利用粉煤灰636万吨,占全国粉煤灰总利用量的32.9％。其中墙体材料利用量约520万吨,占建材利用量81％;水泥利用量约100万吨,占16％。
For a long time, the building materials industry has been actively committed to the comprehensive utilization of fly ash. According to incomplete statistics, during the “7th Five-Year Plan” period, the building materials industry used about 30 million tons of fly ash, equivalent to nearly 2,000 million yuan for the construction of ash yards, saving 15,000 acres of land, and saving about 2 million tons of standard coal. In 1989, the building materials industry utilized 6.36 million tons of fly ash comprehensively, accounting for 32.9% of the total fly ash utilization in the country. The wall material utilization is about 5.2 million tons, accounting for 81% of the use of building materials; cement utilization is about 1 million tons, accounting for 16%.
