摘　　要：试验研究了磷渣、早强剂、膨胀剂对灌浆砂浆性能的影响,测试分析了水泥-磷渣-膨胀剂复合胶凝材料的水化热和孔结构。结果表明：以硅酸盐水泥为基材配制灌浆砂浆,磷渣掺量宜控制在20%~30%之间;水泥-磷渣-膨胀剂复合胶凝材料水化放热速率低且放热量小,平均孔径和最可几孔径较小,孔径分布合理,适用于配制灌浆砂浆。The influence of phosphorous slag, early strength agent and expanding agent on the properties of grouting mortar are studied, and the heat of hydration and pore structure of the composite gelled material of cement-phosphorous slag-expanding agent are tested and analyzed. The results show that the grouting mortar with silicate cement is made, with phosphorous slag amount within 20%-30%; The heat of hydration of composite gelled material of cement-phosphorous slag-expanding agent is very low with low heat, and both the average pore size and reasonable pore distribution are small, which is suitable to make grouting mortar.
