以硅酸盐水泥为主要胶凝材料,成功研制出早强、高强、大流动度、微膨胀、可操作时间长的高性能灌浆料,该灌浆料既能满足传统灌浆料早强的要求,又扩大了应用范围,而且采用了成本低廉的硅酸盐水泥作为主要胶凝材料,极大地降低了生产成本。%Taking the portland cement as the main cementitious material,the paper successfully researches the high-performance grout with the early strength,the high strength,the large mobility,the light expansion,and long operation time,the grouting material can not only meet early strength demand of traditional grouting material and extend application scope,but also adopts low-cost silicate cement as main cementing material,which greatly reduces production cost.
