摘　　要：主要研究了氧化还原体系种类及配比等因素对丙烯酸镁防水灌浆材料固化时间、固砂体抗压强度和凝胶体吸水膨胀率的影响。结果表明:氧化剂和还原剂用量增加都能缩短固化时间,氧化还原体系对固砂体抗压强度、凝胶体吸水膨胀率影响不明显,氧化剂、还原剂用量及配比对凝胶体吸水膨胀性有一定影响,凝胶体固化物孔隙数量与氧化剂、还原剂用量有关。The article mainly studies the effects of the types and proportions of redox system on the curing time,compressive strength of sand solid and water absorption expansion of the gel of acrylate magnesium waterproofing grouting material.The results show:the increase of oxidant and reductant can shorten the curing time;the effect of redox system on the compressive strength of sand solid and water absorption expansion of the gel is not obvious;the amount and proportion of oxidant and reductant have certain influence on the water absorption expansion of the gel;the pore quantity of the gel condensate is related to the amount of oxidant and reductant.

关 键 词：丙烯酸镁防水灌浆材料 氧化还原体系 固化时间 抗压强度 吸水膨胀率
