摘　　要：为了研究不同配合比对预应力孔道灌浆材料的影响,向水泥中加入不同掺量的高效减水剂、膨胀剂以及外掺剂,并测得在不同养护时间下的抗折强度、抗压强度以及静止初始,30 min,60 min的流动度,得到了最佳减水剂的掺量和不同种类掺合料对灌浆材料流动度、抗折强度和抗压强度的影响规律。In order to research different mixture ratio of prestressed duct grouting materials,to cement added with different dosage of water reducer,expansive agent and additive,and measured in curing time,the compressive strength and flexural strength,and static,30 min,60 min flow degree. Get the best reduction agent content and doped with different amount of powder of grouting material fluidity,compressive strength and flexural strength were investigated.

关 键 词：预应力孔道 灌浆 流动度 抗压强度 抗折强度
