Abstract：In the experiment,the mass of the water,the cement,the mortar and aluminum paste are fixed,the proportion of sedimentary fly ash,desulfurization gypsum and lime is changed. The optimal proportion of sedimentary fly ash aerated concrete is determined according to the principle of the maximum compression strength and the bending strength. The test is divided into 2 stage of initial test and reexamine:the preliminary test is made to determine the approximate range of the optimum contents. The further test is done to obtain best proportion. The experimental results show that the optimal proportion of sedimentary fly ash,lime and desulfurization gypsum is 83%~84%,13%,3%~4%.
