【摘要】 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。更多还原

【Abstract】 It is very important to improve the groutability and the durability of grouting material applied to grouting engineering,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 introduced in the use of grouting engineering,especially in medium and fine sand formation.更多还原
