| 摘 要： | 研究了以粉煤灰替代偏高岭土为主要原料制备的地质聚合物胶凝材料的抗压强度,并用SEM观察其微观形貌。结果表明,用含有质量分数20%、40%、60%粉煤灰替代偏高岭土为原料制得的地质聚合物,其受压破坏面物相成分较杂乱,有较多的球状粉煤灰颗粒和裂缝;与单用偏高岭土作原料制备的地质聚合物相比,试样各龄期抗压强度值均不高。

| Abstract: | The geopolymer cementitious material that is completely different from the portland cement.It was successfully synthesized using aluminum silicate raw materials at low temperature,which activated by alkali.It has many excellent performance,such as,higher early age strength,better volume stability and durability.This paper gives analyses to the mechanisms and microstructure of fly ash and metakaolin based geopolymer cementitious material by means of SEM.The result indicated that:containing 20%,40%,60% fly as... |
