利用X射线荧光光谱仪、XRD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。通过选用确定组分的基础蒸压循环流化床粉煤灰混凝土砌块配方,并用正交设计实验方法安排和组织试验,研究了养护制度对蒸压循环流化床粉煤灰混凝土砌块抗压强度等性能的影响。实验结果表明,在蒸压养护制度中,影响循环流化床粉煤灰混凝土试块抗压强度的主要因素为升温时间,因素的主次顺序为：升温时间〉恒温时间〉降温时间〉恒温压力。其最佳的蒸压养护制度：升温时间3h,恒温时间6h,恒温压力1MPa,降温时间1.5h。

With X-ray fluorescence spectrometry and X-ray diffraction, the chemical compositions of circulating fluidized bed fly ash are analyzed. We work out the prescription for producing the circulating fluidized bed fly ash concrete block, and study the influences of the autoclaved conditions for the compressive strength of concrete block with the orthogonal design method. The results show that the key factors of the caring system are as following in order： heating time, constant temperature time, temperature decreasing time and constant pressure. The best autoclaved conditions are heating time 3 hours, constant temperature time 6 hours, constant pressure 1 MPa, temperature decreasing time 1.5 hours.
