建筑业的发展促进了墙体材料的改革,新的墙体材料的出现又推动了建筑业的前进。当前国外墙体材料的发展,有一个显著的特点,是各国根据本国资源情况,加强对工业废渣的综合利用,开辟墙体材料工业新的原料来源,增加品种,提高产品性能。现将几种主要工业废渣一火电厂煤灰渣,煤矸石,高炉矿渣,铜矿尾矿等在墙体材料工业中的应用情况简介如下。
The development of the construction industry has promoted the reform of wall materials. The emergence of new wall materials has also promoted the construction industry. At present, the development of foreign wall materials has a notable feature. All countries, in accordance with their own resources, have strengthened the comprehensive utilization of industrial waste residue, opened up new sources of raw materials for the wall materials industry, increased varieties, and improved product performance. Several major industrial waste slags are introduced as follows: Coal ash slag, coal gangue, blast furnace slag, copper tailings, etc. in thermal power plants.
