在我国,墙体材料约占整个房屋建筑材料的70%,其中粘土砖在墙材中仍居主导地位,生产实心粘土砖所需的粘土资源更属可耕地中较优质的粘土,因此,其对土地资源的破坏极为严重。另据测算,在我国用实心粘土砖建造的房屋,单位建筑能耗相当于气候条件相近的发达国家的2～3倍。而目前我 In our country, the wall material accounts for about 70% of the whole building materials. Among them, the clay brick still dominates the wall material, and the clay resources needed to produce the solid clay brick are more clay in the arable land. Therefore, The destruction of land resources is extremely serious. According to another estimate, in China with solid clay brick houses built, the unit building energy consumption is equivalent to similar weather conditions in developed countries 2 to 3 times. And at the moment
