一粘土砖是我国目前主要的墙体材料。建国以来,我国粘上砖产量大幅度提高,总产量居世界首位。1982年,全国粘土砖产量为1900多亿块,约占墙体材料的93%。据测算,全国每年需产2200亿块砖,才能满足城乡建设需要。目前缺口约300亿块。而发展粘土砖,又面临着土源、能源不足的严重问题。 A clay brick is currently the main wall material in China. Since the founding of the People’s Republic of China, China’s production of bricks has greatly increased, and its total output ranks first in the world. In 1982, the country’s clay brick production was more than 190 billion pieces, accounting for about 93% of the wall material. According to calculations, it is necessary to produce 220 billion bricks a year to meet the needs of urban and rural construction. The current gap is about 30 billion. The development of clay bricks, in turn, is faced with serious problems of insufficient land resources and energy.
