Purpose: In this study, a grout material mixed using non-alkaline silica-based materials, which is an eco-friendly injection material to stabilize ground, is investigated to improve conventional problems. Method: The homogel specimens of Eco-Friendly Non-Alkaline Silica Sol (ENASS) and L.W. and S.G.R., representative silicate grouting are manufactured. Physicochemical and engineering properties of the specimens are evaluated in laboratory with uniaxial compression strength, hydraulic conductivity, shrinkage, chemical resistance, elution, fish poison, waste leaching. Result: Laboratory test results show that the ENASS was superior in all aspects compared to the existing injection matirial. The suitability of the grout material with ENASS is investigated with filed tests. Conclusion: The results of laboratory and field tests demonstrates that the grout material with ENASS is eco-friendly material that increases the strength, decreases the permeability, and discharges pollutants without leaching.
연구목적: 본 연구에서는 기존 주입공법의 문제점을 개선하기 위한 친환경적인 주입재를 개발하고 시험을 통해 현장 적용성을 확인하기 위한 연구를 수행하였다. 연구방법: 친환경 주입재와 기존 주입재(L.W, S.G.R)의 호모겔 공시체를 각각 제작하고, 실내시험(일축압축강도, 투수계수, 수축성, 내화학성, 용출성, 어독성, 폐기물공정)을 실시하여 물리화학적 및 공학적 특성을 비교·검토하였다. 연구결과: 실내시험 결과 친환경 주입재가 기존 주입재에 비해 모든면에서 우수하였으며 주입재료로서 실제 현장에서 시공적합성을 실험하고 지반개량 효과를 확인할 수 있었다. 결론: 본 연구에서 사용된 주입재는 강도증가 및 투수성 감소 등의 기본적인 물성을 만족하면서 친환경적인 특성을 가지고 있어 지반의 조건과 적용에 관계없이 범용적으로 사용이 가능한 재료로 판단되었다.
