摘　　要：研究了废砂浆粉基本性能及作为水泥混合材对水泥胶砂主要性能的影响,包括粉磨性能、标准稠度需水量、流动性和强度。结果表明,掺入废砂浆粉的混合水泥胶砂流动度有所下降,标准稠度需水量增加。而且废砂浆粉的细度和掺量都会影响强度,混合水泥折压比有所增长,材料延性较好。The article studies the basic properties of the waste mortar powder and the influence of it as a cement ad?mixture on the main properties of cement mortar, including grinding performance, water amount of normal consisten?cy, mobility and strength. Results show that waste mortar powder of fluidity of cement mortar is decreased and water amount of normal consistency is increased. And the fineness and content of waste mortar powder will affect the strength of cement mortar, bend-press ratio is increased, the material ductility is better.

关 键 词：废砂浆粉 强度 粉磨性能 细度 掺量
