Abstract: In order to solve the problem that the excellent selection of grouting materials were in the process of the collapsible loess, a five-factor and four-level orthogonal test scheme was designed.The effect of anhydrous sodium surfute, bentonite, fly ash and hydrate lime on the properties of grouting material was systematically studied.The corrosion resistance and micro experiments were performed on four different proportions.The result showes that comparing to water cement ratio on the initial discosity and drainage rate,the stone body's impact of compressive strength is most pronounced,and it is decisive for the performance of the slurry,so obtained the otimal formula of grouting that is suitable for the losse region.The optimized slurry lithosomes are more dense than pure cement slurry, and they are more resistant to corrosion.
