摘　　要：选用矿粉、粉煤灰为主要原料,通过碱激发剂形成胶凝体结构的无机高性能高分子胶结材料,研究了矿物掺量、激发剂、减水剂、缓凝剂、塑性膨胀剂A对注浆材料性能的影响,确定了地聚合物注浆材料的最优配合比为:矿粉掺量30%,粉煤灰掺量70%,FDN减水剂掺量1%,缓凝剂BL掺量1%,激发剂模数1.6、掺量8%,塑性膨胀剂A掺量0.1%。制备的用于道路修复加固的地聚合物注浆材料较好地解决了传统水泥注浆材料耐久性差、使用寿命短等问题,且实际工程应用效果良好。Inorganic high performance polymer cementing material of gel structure was formed with alkali activator by select- ing slag and fly ash as the main raw material. The effect of mineral admixture,activator, reducing agent,retarder, plastic expansion agent A on the properties of grouting materials was studied and the optimal mix proportion of polymer grouting material was deter- mined： slag powder content of 30%,the amount of fly ash of 70%,FDN reducing agent dosage of l % , retarder BL content of 1%, modulus of activator of 1.6,dosage of 8%,plastic expansion agent A content of 0.1%. The geopolymer grouting material prepared for road repair and reinforcement is a good solution to the problems of poor durability, short service life and so on. And the actu- al engineering application effect is good.
