1981年初我们承担了前国家建工总局下达的工业废渣小型混凝土空心砌块建筑研究的任务,其要求:①小砌块混凝土的水泥用量不超过200公斤/米~3;②小砌块外墙热工性能接近49厘米厚砖墙;③小砌块建筑造价相当于砖混建筑。并要求在当年进行工程试点。为了可以直接引用南方有关省市小砌块材性方面的试验数据,内墙我们仍采用:主块390×190×190毫米;辅助块190×190×
In early 1981, we undertook the task of research on the construction of industrial solid waste small concrete hollow block buildings issued by the former State Administration of Industry and Construction. Its requirements: 1 The cement content of small block concrete shall not exceed 200 kg/m~3; 2 The external wall of small blocks Thermal performance close to 49 cm thick brick wall; 3 small block construction cost is equivalent to masonry construction. And requested that the project be piloted in the same year. In order to directly quote the experimental data on the properties of small blocks in southern provinces and cities in China, the internal wall is still used: the main block is 390×190×190 mm; the auxiliary block is 190×190×
