在C35玻化微珠保温混凝土配合比的基础上，将石屑以0、20％、40％、60％、80％、100％的质量替代率替代河砂，通过分析六种不同石屑替代率对玻化微珠保温混凝土流动性、黏聚性、保水性、抗压强度和导热系数的影响，综合确定石屑代砂的最优替代率。试验结果表明：随着石屑替代率的增加，保温混凝土的流动性和黏聚性逐渐变差，但保水性良好；保温混凝土的抗压强度大体上呈增加趋势，而导热系数几乎没有变化；综合分析确定石屑代砂的替代率为60％时，保温混凝土的工作性、抗压强度和导热系数比较好。

Based on the mixture ratio of C 35 glazed hollow bead insulation concrete , stone chips are substituted for river sands by the quality replacement rates 0、20%、40%、60%、80%、100%in the test .Six different replace-ment rates of stone chips are studied by analyzing the impact of mobility ,cohesiveness ,water retention ,compressive strength and thermal conductivity of glazed hollow bead insulation concrete , then the optimal replacement rate of stone chips are determined .The results indicate that:with the increasing of replacement rates of stone chips , the mobility and cohesiveness become worse , while water retention is better , the compressive strength increases sub-stantially, while the thermal conductivity is almost no change .Finally, the best replacement rate of stone chips is 60%, and the work-ability, compressive strength and thermal conductivity of thermal insulation concrete are better .
