摘　　要：本研究以矿渣和粉煤灰硅酸盐固体废弃物为原料,以氢氧化钠调节不同模数的工业水玻璃为激发剂,制备高效、廉价、环保的地质聚合物路面修补材料来代替水泥路面修补材料。采用维卡仪、场发射扫描电子显微镜(FESEM)、万能材料试验机等分析方法,研究了激发剂模数、激发剂掺量、水固比以及掺合料对固废地质聚合物路面修补材料性能的影响,通过配合比的调控达到地质聚合物路面修补材料性能可控。研究结果表明:凝结时间可以通过配合比的调节进行控制,最终可将初凝时间控制在25~198min,终凝时间控制在45~267min,当稻壳灰和偏高岭土掺量均为10%时,地质聚合物路面修补材料性能最好。In this study,an efficient,cheap and environmentally friendly geopolymer pavement repair material was prepared to replace cement pavement repair material with Portland solid waste of slag and fly ash as raw materi⁃als and industrial sodium silicate with different modulus adjusted by sodium hydroxide as activator.It studies the ex⁃citing agent module,excitation agent dosage,water solid ratio and the admixture on the properties of solid waste geo⁃logical polymer patching material,through mixing ratio regulation to geological polymer patching material perfor⁃mance under control with Vicat instrument,field emission scanning electron microscope(FESEM),and universal ma⁃terial testing machine.The results show that the setting time can be controlled by adjusting the mixing ratio,and the initial setting time can be controlled from 25 to 198min,and the final setting time can be controlled from 45 to 267min.When rice husk ash and metakaolin are both 10%,the performance of geopolymer pavement repair material is the best.
