采用碱激发偏高岭土/粒化高炉矿渣（GBFS）基地质聚合物制备了有机树脂（OR）增强的地质聚合物。通过掺杂量为1重量%的OR的地质聚合物复合材料在不同的固化时间显示出最高的压缩和弯曲强度。量热分析结果表明，由于OR的加入加快了地聚合速率，在1~3d的反应初期，地聚合物复合材料的反应热远高于地聚合物。提出了合理的加固机制。
A novel method for preparation of alkali-activated metakaolin/granulated blast furnace slag (GBFS)-based geopolymer reinforced by organic resins (OR) was reported. The geopolymer composites by doping an amount of 1 wt% OR displayed the highest compressive and flexural strengths at the different curing times. The calorimetry results showed that the reaction heats of the geopolymer composites at the early reaction stage of 1~3d are much higher than that of geopolymer due to the geopolymerization rate to be accelerated by incorporation of OR. A reasonable reinforced mechanism was proposed.
