미생물 처리 방법이 바이오그라우트에 미치는 영향

국문 초록 (Abstract)

본 연구에서는 친환경적인 그라우트재의 개발을 위하여 연약지반에 대한 바이오그라우트 가능성을 확인하고, Bacillus Pasteurii 균을 이용하여 탄산칼슘 침전 효과를 분석하였다. 연약지반에 미생물의 탄산칼슘 침전을 이용하여 바이오그라우트에 미치는 영향을 알아보기 위해 4가지 시료의 조건(멸균 시료, 비멸균 시료, 반응용액과 미생물용액의 선처리 혼합시료, 반응용액과 미생물용액의 후처리 혼합시료)으로 실험되었다. 전자현미경(SEM), EDX와 X선 분석 회절기(XRD)를 이용하여 연약지반 시료의 분석을 수행하였고, 이러한 연구결과를 바탕으로 탄산칼슘 침전을 이용한 미생물 처리 공법은 바이오그라우트의 특성을 개선하였다.

The purpose of study is to understand the possibility of biogrout of soil induced by bacteria. Microbial Calcium Carbonate Precipitation(MCP) has been analysed using the microorganism Bacillus Pasteurii. In order to understand the biogrout of soft ground treated with microbial calcium carbonate precipitation, four types of specimens(sterilization soil, non-sterilization soil, reaction solution and microorganism solution with pre-treatment mix and reaction solution and microorganism solution with post-treatment mix) were made. Scanning Electron Microscope(SEM), EDX and X-ray diffraction(XRD) analyses were performed on the soft ground specimens. On the basis of the preliminary results, it appears that microbial treatment methods using calcium carbonate precipitation may be possible to improve property of biogrout.
