Abstract

Products of building materials are made from sand, stones, cement, powdered coal ash and constructive rubbish. These products have not been looked as good ones by many constructive institutes and businessmen and consumers. Therefore, factories dedicated to such products find it very hard to survive in the market. The main causes for the above are as follows. First, some departments of local governments and some constructive institutes do not look it as an important thing. The second is that our country makes relevant law and rule behind time. The third is that it is not serious for some local governments to do something according to the relevant law and rule. The fourth is the price of raw material is higher than normal but the price of product being the same as before. Government should regard it as an important matter, and promote it for publicity. It is necessary for us to turn the thoughts of building construction into new ideas which are use of ecologic constructive materials in their buildings among constructive institutes and businessmen and consumers.
