摘要:
采用脱硫石膏-地聚合物作为固化剂固化软土,通过强度试验研究在不同硅铝原料配比时,碱激发剂模数、含量和脱硫石膏的掺量对固化软土抗压强度的影响,并通过扫描电镜试验和X射线衍射试验分析固化软土的微观结构变化。结果表明:脱硫石膏-地聚合物可有效提高软土的抗压强度;碱激发剂的最佳模数和含量分别为0.8和6%;脱硫石膏对地聚合物固化软土的抗压强度有促进作用,硅铝原材料中含有30%矿渣的固化软土抗压强度提升幅度大于100%粉煤灰。地聚合物固化软土生成C-(A)-S-H和N-A-S-H胶结物,加入脱硫石膏后生成了钙矾石,两者共同作用是脱硫石膏-地聚合物提高固化软土抗压强度的主要原因。该研究结果可为地聚合物应用于实际工程中软土地基处理提供参考。
