自1988年国家“两部两局”联合发出限制毁田烧砖、加速墙体材料改革的通知后,小型空心砌块被全国各省市采纳,作为可以代替粘土砖的首选墙体材料,得到了快速的发展。据不完全统计1996年全国砌块总产量约为2500万立方米,各类砌块建筑达5000万平方米,近十年来的增长率都在20％左右。这固然是可喜的成绩,但与被改革对象粘土砖比,仍旧是差距悬殊,望尘莫及。在砌块建筑推广的过程中也遇到不少困难。正如绍兴市反映的情况那样,尽管该市推广砼砌块建筑已有15年历史,建成小区十多个,建筑面积200万 Since 1988, when the national “two bureaus” jointly issued a circular to limit the destruction of bricks and mortar and accelerate the reform of wall materials, small hollow blocks were adopted by all provinces and cities across the country as the preferred wall material that could replace clay bricks. rapid development. According to incomplete statistics, the nation’s total block production in 1996 was about 25 million cubic meters, and various types of block construction reached 50 million square meters. The growth rate in the past decade was about 20%. This is indeed a gratifying achievement, but it is still far behind the reformed clay bricks. There are also many difficulties encountered in the promotion of building blocks. As reported by Shaoxing City, despite the fact that the city has promoted the use of block building for 15 years, more than a dozen built-up communities have been constructed, with a building area of ​​2 million.
