지반주입재의 압축강도에 영향을 미치는 물리·화학적 요소에 관한 연구

To be preparing of that carelessness, new type of tunnel driving method and tunnel aid method are not only in common use of the subway but also obtaining good results within the country. In this paper, an extensive uniaxial compressive strength test was carried out to examine the variation of compressive strength for home-gel of grouting materials. It was observed that the compressive strength of Sodium Silicate-Cement Grouts varied according to mixing method. The compressive strength increases with using Circulation- Grinding-Mixing Method, and this trend is increasingly noticeable to a low molar ratio(calcium hydroxide /natrium oxide).
