摘要
以矿粉、粉煤灰为原料,以氢氧化钠为激发剂,制备了粉煤灰-矿渣地聚合物,探讨了不同碱浓度对粉煤灰-矿渣地质聚合物的抗压强度的影响;并以此粉煤灰-矿渣地聚合物与不同比例的黄土混合,测试它们在不同碱浓度条件下的抗压性能。结果表明,粉煤灰-矿渣地聚合物可取代水泥,用作高抗压强度的搅拌桩材料。
In order to study the basic properties of fly ash and slag geopolymer used for mixing pile,slag and fly ash as raw material,sodium hydroxide as exciting agent,fly ash and slag geopolymer was prepared. The effect of different alkali concentration on the compressive strength of fly ash and slag geopolymer was discussed. Under different alkali concentration,the compressive properties of slag and fly ash geopolymer of which blended with different proportion of loess were tested. The results show that the fly ash and slag geopolymer can replace cement,used in high strength material of mixing pile.
