Abstract

This study introduces strength characteristics of the anti-washout grouting material using viscous modifiers and its characteristics mixed with coarse materials. Especially, this study focused on the strength characteristics of the grouts mixed with sea water. It is found that the anti-washout grout mixed with sea water has enough strength and good resistance to segregation just like that with fresh water. Also, a small scale test was performed to evaluate the solidification characteristic of the anti-washout grout mixed with coarse fill materials. It is also found that the strength of anti-washout grout mixed with coarse fill materials is greater and better segregation resistance than those of conventional grout with fill materials.

본 연구에서는 계면활성제계 개질제를 이용하여 수중에서 재료분리가 발생하지 않으면서도 유동성을 충분히 갖는 수중 불분리성 점탄성 그라우트재와 일반 그라우팅 재료의 강도 특성과 속채움 보강 재료로서의 특성을 분석하였다. 특히, 해수를 활용하여 점탄성 그라우팅 재료를 제작하는 경우에 대해 중점적으로 시험을 수행한 결과, 담수를 사용하여 그라우트 재료를 제작하는 경우와 마찬가지로 수중 불분리성 특성을 잘 나타내었으며, 이에 따른 균질한 점탄성 그라우트재의 강도를 확보할 수 있을 것으로 평가되었다. 또한, 모형시험을 통해 그라우트재의 침투성을 이용하여 속채움 골재의 보강특성을 평가한 결과, 수중 불분리성 그라우팅 재료는 일반 그라우트재와 비교하여 충분한 강도가 발휘되었으며, 점성에 의한 수중 불분리 특성으로 속채움 보강재로서 좋은 시공 품질을 확보할 수 있을 것으로 평가되었다.
