摘   要：研究了以矿渣、钢渣、石膏为主要组分的固废基胶凝材料（SWM）掺量（0~60%）对水泥净浆、胶砂和混凝土性能的影响。结果表明：随着SWM掺量的增加，水泥净浆达到设计初始流动度所需的减水剂用量增大，流动度2 h经时损失先增大后减小；SWM的掺入降低了胶砂试件的抗折和抗压强度；掺入SWM后，混凝土达到设计初始坍落度所需的减水剂用量增加，保坍性能降低，排空时间增加，初凝和终凝时间延长；与基准组相比，掺SWM混凝土试件的抗压强度较低；随着SWM掺量从10%增至60%，混凝土试件的3 d、7 d抗压强度基本呈降低趋势，28、60、90 d抗压强度呈先增大后减小再增大的趋势。

Abstract: The influence of the content (0~60%) of solid waste based cementitious materials (SWM) with slag, steel slag, and gypsum as the main components on the properties of cement slurry, cement mortar, and concrete was studied. The results show that with the increase of SWM content, the amount of water reducing agent required for the cement slurry to reach the design initial flowability increases, and the 2 h loss of flowability first increases and then decreases. The addition of SWM reduces the flexural and compressive strength of the cement mortar specimens. After adding SWM, the amount of water reducing agent required for the concrete to reach the initial design slump increases, the slump retention performance decreases, the flow time increases, and the initial and final setting times are prolonged. Compared with the benchmark group, the compressive strength of concrete specimens mixed with SWM is lower. As the SWM content increases from 10% to 60%, the 3 d and 7 d compressive strength of concrete specimens basically show a decreasing trend, while the 28 d, 60 d, and 90 d compressive strength show a trend of first increasing, then decreasing, and then increasing again.
