【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。
[Abstract]:Fly ash and slag geopolymers were prepared by using mineral powder and fly ash as raw materials and sodium hydroxide as activator. The effect of different alkali concentration on compressive strength of fly ash and slag geopolymers was discussed.The fly-ash and slag geopolymers were mixed with different proportion of loess to test their compressive properties under different alkali concentrations.The results show that fly ash-slag polymer can replace cement and be used as mixing pile material with high compressive strength.
