| Abstract: | Lead-zinc tailings were used to produce aerated concrete.The effects of water-binder ratio,casting temperature and aluminum powder content on the gas forming 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. |
