烧结粘土砖做墙体材料由来已久.它不仅强度高、抗水性强、透气性及耐火耐久性好,还有其它许多优良的性能,且能就地取材,原料来源广阔,故在古代很快得到发展,并沿用至今.但是烧结粘土砖生产时能源消耗很大,对土质要求较高,有些地区缺乏质量较好的粘土和燃料,往往毁田烧砖和毁林烧砖,造成严重的不良后果.我省年产烧结粘土砖19亿块,其中轮窑、隧道窑烧砖10亿块,每万砖标准煤耗1500公斤;小土窑用煤烧砖4亿块,每万砖标准煤耗达3000公斤以上;小土窑用木柴烧砖5
Sintered clay bricks have been used for a long time as a wall material. It not only has high strength, strong water resistance, good air permeability and durability, but also many other excellent properties. It can be locally sourced and has a wide source of raw materials. It has been developed rapidly and is still in use today. However, the energy consumption of sintered clay bricks is very large, and the soil quality requirements are relatively high. In some areas, clay and fuel with good quality are lacking, which often destroy land and burn bricks, and destroy trees and burn bricks, causing serious problems. Adverse consequences: Our province annually produces 1.9 billion pieces of sintered clay bricks, including 1 billion bricks burned in tunnel kiln and tunnel kiln, 1,500 kg standard coal consumption per 10,000 bricks, 400 million coal bricks in small earth kiln, and standard coal consumption per 10,000 bricks. 3000 kg or more; small earth kiln firewood with brick 5
