摘　　要：介绍了一种新型水泥基封孔灌浆料的制备与性能试验,通过普通硅酸盐水泥与硫铝酸盐水泥复配,优化水泥浆体的矿物组分,配制出既具有早强、高强特性,又具有可灌性好、微膨胀、凝结时间可调的灌浆材料。A new cement - based plugging grouting material is produced and tested in laboratory. The compound of sulphoaluminate and ordinary portland cement optimizes the mineral composition, which not only has high - early strength, super high - strength characteristics, but also has good plug ability, expansive character and adjustable time of setting.
