为解决三峡库区移民工程墙材问题，武汉工业大学马保国副教授等针对当地资源情况，对风化花岗岩砂－磷矿渣－石灰加气混凝土的生产工艺参数和微观结构进行了研究，利用风化砂生产加气混凝土在国内外均属首次。结果表明，其适宜的配合比范围为：风化砂５０％～６０％，磷矿渣１? In order to solve the problem of wall materials of resettlement engineering in the Three Gorges Reservoir Area, Associate Professor Ma Baoguo of Wuhan University of Technology, etc. According to the local resources, the production process parameters and microstructure of weathered granite sand-phosphate slag-lime aerated concrete were studied, Aerated concrete is the first time at home and abroad. The results showed that the suitable proportion of the mixture ranged from 50% to 60% of weathered sand and 1%
