摘　　要：为了实现搅拌站废浆的再利用,研究了不同含固量(3%~15%)废浆等质量取代0~100%的水对砂浆流动度及力学性能的影响。结果表明:废浆中存在的C3S、C2S等矿物成分使其具备在混凝土中应用的可行性;随着废浆掺量的增加,砂浆的流动度基本呈减小趋势;废浆的掺入能在一定程度上使砂浆的微观结构更密实,从而提高砂浆的力学性能,尤其是28 d抗压强度。In order to realize the reuse of waste slurry from mixing plants,the effects of replacing 0~100%water by waste slurry with different solid content(3%~15%)on the fluidity and mechanical properties of mortar were investigated.The results show that the existence of C3S,C2S and other mineral components in the waste slurry makes it feasible to be applied in concrete.With the increase of the replacement rate of waste slurry,the fluidity of mortar basically shows a decreasing trend.The incorporation of waste slurry can make the microstructure of mortar denser to a certain extent,so as to improve the mechanical properties of the mortar,especially the 28 d compressive strength.
