利用X射线荧光光谱仪、X RD等检测手段对循环流化床粉煤灰进行化学成分定性和定量分析，然后确定配合比：粉煤灰65％，水泥12％，石灰20％，石膏3％。主要研究了在蒸压养护条件下，不同水料比、不同铝粉添加量、不同无机外加剂硫酸钠、氯化钙添加量对加气混凝土砌块容重和强度的影响，研究发现最佳水料比为0．65，最佳铝粉掺量为0．1％，无机外加剂硫酸钠对加气混凝土砌块的容重和强度影响不大，而添加0．25％的氯化钙比无外加剂条件下强度提高了40％，达到4．55 M Pa ，且容重为910 kg/m3，随着氯化钙量的增加，强度反而下降。

In this article ,chemical compositions of circulating fluidized bed fly ash were gualitative and guantitative analyzed by using X-ray fluorescence spectrometry and X-ray diffraction ,then confirmed the suitable match ratio :fly ash 65 percent ,cement 12 percent ,lime 20 percent ,gypsum 3 percent . Primarily studied on autoclaved condition ,the effects of different amounts of water-binder ratio ,Al powder addition ,inorganic admixture (sodium sulphate ,calcium chloride) addition on volume weight and compression strength .The result show that the best water-binder ratio was 0 .65 ,the best Al powder addition was 0 .1 percent ,sodium sulphate was less effect on volume weight and compression strength of aerated concrete ,however compare with non-admixture ,compression strength raised by 40 percent while adding 0 .25 percent calcium chloride ,it reached 4 .55 MPa and 910 kg/m3 ,with increasing of addition of calcium chloride ,the compression strength of aerated concrete decrease .
