摘　　要：用铅锌尾矿生产加气混凝土.分析了水料质量比、浇注温度和铝粉膏的掺量对加气混凝土发气的影响,以及铅锌尾矿、水泥和调节剂对加气混凝土强度的影响.确定了优化的工艺方案和配方.按优化的工艺和配方制备的加气凝土的抗压强度和抗冻性达到了B06级合格品要求,导热系数、干燥收缩值和放射性满足国家标准要求.Lead-zinc tailings were used to produce aerated concrete. casting temperature and aluminum powder content on the gas forming The effects of water-binder ratio, behavior, and those of lead-zinc tailing content, cement content and conditioning agents on the compressive strength of the aerated concrete were investigated. Optimal raw material formulation and procedure were determined for the aerated concrete. The compressive strength＇ and frost resistance of the aerated concrete made by the optimal raw material formulation and procedure conform with the requirements of aerated concretes of B06 grade, and thermal conductivity, drying shrinkage and radioactivity conform with the relevant national standards of China.
