초록

화학적 지반보강은 재료의 화학적 반응을 통해 지반의 역학적 성능을 확보하는 것을 의미한다. 기존에 활용되는 지반보강 재료는 제조 및 활용 간 대기오염, 지하수 용출로 인한 pH 변화 및 생태계 교란 등의 문제가 제기되었다. 따라서, 본 연구에서는 친환경 지반보강을 위해 우유로부터 기원된 카제인 폴리머로 처리된 시료의 공학적 성능이 분석되었다. 공학적 성능 분석은 일축압축강도 및 투수계수 측정을 통해 수행되었다. 활용된 시료는 주문진 표준사, 화강풍화토, 연약지반 시료이며 시료 유형에 따른 일축압축강도 및 투수계수가 분석되었다. 분석 결과, 카제인 폴리머의 함량 및 시료 유형에 따른 유의미한 상관관계가 도출되었다. 본 연구에서 도출된 결과는 카제인 폴리머의 지반 보강 적용 시 기초자료로 활용될 수 있을 것으로 판단된다.

Chemical ground reinforcement involves enhancing the mechanical properties of soil through chemical reactions. Existing ground reinforcement materials pose challenges, including environmental pollution during production and use, pH fluctuations caused by leaching into groundwater, and ecological disturbances. This study investigates the engineering performance of soils treated with casein polymer, a milk-derived, eco-friendly reinforcement material. The performance assessment was carried out by measuring unconfined compressive strength and hydraulic conductivity across different soil types, including Jumunjin sand, granite weathered soil, and soft soils. The analysis examined the relationship between unconfined compressive strength, hydraulic conductivity, and soil type. The findings indicate significant correlations based on the concentration of casein polymer and soil type. The outcomes of this study provide foundational data for the application of casein polymer in soil reinforcement efforts.
