改性灌浆水泥及在帷幕灌浆中的应用

A modified grouting cement and its application to curtain grouting

改性灌浆水泥是以普通硅酸盐水泥或硅酸盐水泥熟料为主，掺入适量的新型灌浆材料。经试验和施工表明，其主要性能均优于普通水泥和湿磨水泥， 对帷幕的防渗能力可起到加强作用， 在以后的施工中将会得到更广泛的应用。

The modified grouting cement is made of taking ordinary Portland cement or ripe Portland cement as the dominant material and adding some new grouting material. The test and construction shows that its performance excels ordinary cement and wet grinding cement, and it can raise seepage prevention ability of the curtain grouting. The cement can find wide use on construction in future.
