以碱激发固体废弃物粉替代胶凝材料制备防水砂浆,研究固废物细粉含量对防水砂浆力学性能、收缩率与吸水率的影响,探讨消泡剂的加入量对于防水砂浆的吸水率的影响规律,研究有机硅防水材料掺量对防水砂浆吸水率与抗渗性能的影响规律。研究结果表明,当固废物含量为胶凝材料掺量为胶凝材料的40%,胶砂比为1∶3,消泡剂的加入量为0.02%,有机硅材料掺量为3.3%时,防水砂浆的性能达到最佳,并且从微观结构上防水机理进行解释。
The alkali-activated solid waste powder was used instead of the cementitious material to prepare waterproof mortar. The effect of the content of solid waste on the mechanical properties, shrinkage and water absorption of waterproof mortar was studied. The influence of defoamer addition on the water absorption of waterproof mortar Law, study the effect of the content of silicone waterproof material on water absorption and impermeability of waterproof mortar. The results show that when the content of solid waste is 40% of the cementitious material, the ratio of mortar to sand is 1: 3, the amount of defoaming agent is 0.02% and the amount of silicone material is 3.3% Waterproof mortar to achieve the best performance, and from the microscopic waterproof mechanism to explain.
