小砌块生产和应用,到现在已有一百多个国家。美国小砌块年产量达40亿块,约占其墙体材料总产量的30％,其中混凝土小砌块占房屋总面积的33％,占住宅建筑的50％,日本1949年从美国引进小砌块技术后,发展较快,目前年产量达13亿块。以大板为主要墙体材料的苏联,近年来也大量发展小砌块,其年产量已占粘土砖的27％左右.其他如加拿大,意大利,英国,西德,法国,比利时等国家,小砌
The production and application of small blocks has now reached more than 100 countries. The annual output of American small blocks amounts to 4 billion pieces, accounting for about 30% of the total output of its wall materials. Among them, small concrete blocks account for 33% of the total area of houses and 50% of residential buildings. Japan introduced small quantities from the United States in 1949. After the block technology, it has developed rapidly and currently has an annual output of 1.3 billion. The Soviet Union, which uses large slabs as its main wall material, has also developed a large number of small blocks in recent years. Its annual production has accounted for about 27% of the clay bricks. Others such as Canada, Italy, Britain, West Germany, France, Belgium and other countries, small Build
