Abstract

The present invention relates to a method for manufacturing building material appliances by using cullets as main raw material, which belongs to the fields of urban garbage burnt ash and industrial slag treatment and biological environment. In the method, firstly, an auxiliary agent is manufactured, and then, glass is crushed and fine ground so as to obtain glass powder; finally, the glass powder is mixed with the auxiliary agent, fly ash and water glass according to a certain mass ratio, uniformly stirred, pelletized and calcined so as to obtain artificial light aggregate used as concrete aggregate. The technology similar to the method can be used for manufacturing sintering tiles and used as filtering material in water treating equipment. The method of the present invention can convert urban garbage, industrial residue, the sludge of water treating plants, etc. into resources, develop and produce various building material products, can be used for construction engineering and environmental engineering, save resources and energy sources, improve the environment and have good social and economical benefit.

Description
