新型建筑材料与传统建筑材料相比,具有很高的社会经济效益: 一、节约能源建材工业是耗能大户之一,每年耗能大约5000万吨标煤,其中生产粘土砖耗能就占一半左右。而发展新型建材,既能节约生产能耗,又能节约使用能耗。生产加气混凝土和石膏板的能耗,只为生产粘上砖的60%,假若用加气混凝土或石膏板代替粘土砖的20%建房,每年就能节约标煤270万吨。据日本通产省资料统计,生产直径为150毫米的聚氯乙烯管材的能耗,仅为生产同等口径、同等长度铸铁管能耗的31%。据哈尔滨实测数据,用250毫米厚的
Compared with traditional building materials, new building materials have high social and economic benefits: 1. Energy conservation Building materials industry is one of the major energy-consuming industries. It consumes approximately 50 million tons of standard coal per year, of which clay bricks consume half the energy. about. The development of new building materials will not only save energy consumption but also save energy use. The energy consumption for the production of aerated concrete and gypsum board is only 60% of the production of sticky bricks. If aerated concrete or gypsum board is used instead of 20% of clay bricks, it will save 2.7 million tons of standard coal annually. According to the data of Japan’s Ministry of Industry and Information, the production of PVC pipes with a diameter of 150 mm consumes only 31% of the energy consumption of iron pipes of the same diameter and the same length. According to Harbin measured data, with 250 mm thick
