摘　　要：研究了相同水料比之下,云母废料替代率对砂浆试件工作性能、力学性能以及保温性能的影响。结果表明:云母废料的掺入对砂浆的流动性、力学性能产生了不利影响,且随着替代率的增加不利影响愈加明显。但是,云母废料的掺入对砂浆试件的保温性能有明显改善,云母废料替代率为30%的砂浆较替代率为0的保温性能提高了近10%。The effect of mica waste replacement rate on the working properties,mechanical properties and heat preservation performance of mortar was investigated under the same water to material ratio. The results showed that the mica waste had a neg- ative effect on working performance and mechanical property of mortar, and the effects become obvious with the increase of re- placement rate. However the heat preservation performance of mortar improved obviously with the dosage of mica waste,the mortar specimens replaced with 30% mica waste was improved approximately 10% when compared with the reference group.
