摘　　要：通过对氯氧镁水泥保温材料掺入粉煤灰进行试验并与空白试样对比,研究了在掺入不同量的粉煤灰后氯氧镁水泥保温材料在抗折、抗压强度、耐水性、体积稳定性等性质上所发生的相关变化,进而得到在改性氯氧镁水泥保温材料上较为合适的配合比。试验结果表明:粉煤灰对于改善氯氧镁水泥保温材料的抗折、抗压强度上是有一定效果的,耐水性方面则会有相对显著的提升而在体积稳定性也是具有非常不错的增强,从上述氯氧镁水泥保温材料掺入粉煤灰后所得到的结果可以看出是粉煤灰是一种较为理想的添加剂。The effects of different concentrations of fly ash and magnesium chloride cement insulation materials on the flexural and compressive strength,water resistance and water resistance were studied by mixing fly ash with magnesium chloride cement insulation material and comparing with blank samples.,Volumetric stability and other properties of the relevant changes occurred,and then get modified magnesium oxychloride cement insulation material on the more appropriate ratio.The results show that the fly ash has a certain effect on improving the flexural and compressive strength of the magnesium oxychloride cement insulation material,and there is a significant improvement in water resistance and a very good enhancement in volume stability,From the above-mentioned magnesium oxychloride cement insulation materials mixed with the results obtained after the fly ash can be seen that fly ash is a more ideal additive.
