微硅粉应用于砂性地层注浆工程的可行性分析

在渗透注浆工程中,尤其在中、细砂地层中,提高浆液的可注性并保证一些特殊工程的耐久性非常重要。微硅粉作为注浆材料,其颗粒极细,可注性好,无毒性,浆液结石体强度高,工程耐久性好。通过对一些工程的成功应用进行分析,微硅粉可以作为一种很好的渗透注浆工程注浆材料,尤其在高水位,含中、细砂层地质条件下,微硅粉注浆材料具有广阔的工程应用前景。

Feasibility Analysis of the Silica Fume Applied to Grouting Engineering in Sandy Strata

It is very important to improve the groutability and the durability of grouting material applied to grouting engi- neering, especially in medium and fine sand formation. Silica fume is a grouting material with fine grain, good groutability, no-toxicity, high concretion strength and good durability. By the analysis on successive applications, silica fume is intro- duced in the use of grouting engineering, especially in medium and fine sand formation.
