Experimental Study on Application of Paste-like Grouting Material to Void

공동부 충전재로써 페이스트형 유동화토의 환경 안정성 평가에 관한 실험적 연구

When construction of high pressure jet-grouting is to be performed, it has been reported that applied cement slurry which hasn't got dried out can cause severe environmental pollution, and can flow into near streams and fish farms. Several laboratory tests were performed in this study in order to verify safety of paste-like grouting material that was developed newly to be applied to void in the ground. According to experimental test results, it is proved to be so safe that application of the newly developed flowable grouting material can prevent the materials from spilling into surrounding areas and is not harmful to fishes.
