摘　　要：采用硅灰作为掺合料部分取代石英砂制备聚合物水泥防水砂浆,研究其对防水砂浆力学性能、干燥收缩率及抗渗性能的影响。结果表明,硅灰能有效地提升JF防水砂浆的力学性能及抗渗压力,但会导致砂浆的干燥收缩率增大,影响抗裂性能,因此硅灰的掺量需控制在合理范围内,并非越多越好。Silica ash was used as admixture to partially replace quartz sand for the production of polymer cement waterproofing mortar.The paper studies its effects on mechanical properties,drying shrinkage and impermeability of waterproofing mortar.Results show that silica ash can effectively improve the mechanical properties and impermeability of JF waterproofing mortar,but it will increase the drying shrinkage of mortar and affect the crack resistance.Therefore,the amount of silica ash should be controlled in a reasonable range,not the more the better.

关 键 词：聚合物水泥防水砂浆 硅灰 力学性能 干燥收缩率 抗渗性能
