摘　　要：针对利用煤矸石发电厂的粉煤灰生产的蒸压加气混凝土砌块存在强度低的问题进行试验研究,并借助X射线衍射进行了原因分析。结果表明,粉煤灰中较多的SiO2成分未能进行活化反应是导致砌块强度低的主要原因。通过掺加适量的高效活性组分材料,可有效地提高蒸压加气混凝土砌块的强度。The experimental study is made on low strength of the autoclaved aerated concrete blocks using fly ash of gangue power plant. And the reason is analyzed in virtue of X-ray diffraction. The result demonstrates that the main cause for the low strength of autoclaved aerated concrete blocks is the component SiO2 most of which dose not participate in the activity reaction. The strength of autoclaved aerated concrete blocks can be increased effectively by mix with appropriate amount of high-powered active ingredient.
