蒸养粉煤灰混凝土砌块是用工业废料——粉煤灰、煤渣为主要原料,掺入少量石灰和石膏,加水搅拌,振动成型,用蒸汽养护而成的一种新型墙体材料。 充分利用煤灰、煤渣等工业废料生产建筑材料,不仅为国家节省处理这些废料的费用,而且把无用的煤灰、煤渣变为有用的物资,还大量地节约了堆工业废料占用和制砖挖泥需要的农田。每生产一万立方米砌块,就可以节约农田约八亩半。同时,还可以消除由于电厂粉煤灰排入附近农田或渠道,对农作物生长及工厂设备磨损的危害。
Steam-fed fly ash concrete block is a new type of wall material made of industrial waste—fly ash and coal slag as main raw materials, mixed with a small amount of lime and gypsum, and added with water, stirred, formed by vibration, and cured with steam. Making full use of coal ash, coal cinder, and other industrial wastes to produce building materials not only saves the country the cost of processing these wastes, but also turns useless coal ash and cinders into useful materials, and also saves a lot of industrial waste occupation and brick mining. Mud needs farmland. Every 10,000 cubic meters produced can save about eight and a half acres of farmland. At the same time, it can also eliminate the damage caused by the fly ash from the power plant into the nearby farmland or the channels, and the crop growth and plant equipment wear.
