Practice and study of technique for quick coagulating paste-slurry

The seepage in the foundation of dam has influence on not only the construction , but also the stability of building. So grouting usually was used to control the seeping. The anti-seeping effects of cement slurry, cement-clay slurry , cement-sand slurry and also low-grade concrete to be used in the seeping-stratum with high-rate, large discharge,are generally not good. In this paper , the cement paste-slurry and quick coagulating cement paste-slurry technology were be studied, and used in the anti-seepage project of one foundation of dam in Guangxi province. This technology is a new material and technology to anti-seeping grouting in the seeping-stratum with medium opening and medium rate moving-water.
