摘　　要：以粉煤灰、矿粉两种工业废料为主要原材料,模数为1.2~1.8的水玻璃作为激发剂制备地聚合物。采用五因素四水平的正交试验组成设计方案,测试了水胶比（W）、碱激发剂掺量（S）、矿粉取代率（B）和水玻璃模数（M）在不同水平下试样的流动度、凝结时间、抗压强度和拉伸粘结强度。通过对结果进行极差分析和因素指标分析,得出这种绿色环保型修补材料的组成设计与性能指标之间的关联。综合分析得出,当水胶比为0.28,碱激发剂掺量为0.14,矿粉取代率为0.4,水玻璃模数为1.2时,制备出的地聚合物性能良好,达到绿色环保型建筑修补材料的要求。We used two kinds of industrial waste of Fly ash and blast furnace slag as major raw materials,and modules of sodium silicate ranging from 1.2to 1.8as the activator to manufacture geopolymer.We conducted the orthogonal experiment in five-factor and four-level form,and studied water to binder ratio（W）,alkali-activator proportion（S）,blast furnace slag replacement ratio（B）and the module of sodium silicate（M）on the four essential properties including the fluidity,setting time,compressive strength and tensile bond strength of the geopolymer used in green materials for construction mending.The relation between mix design and performance index of the green repair material were investigated by range analysis and factor analysis.By synthetic analysis,an excellent geopolymer-based green material for construction mending could be manufactured when W,S,Band M were 0.28,0.14,0.4,1.2,respectively.
