Eco-friendly Soil Solidifier Composition with Self-Healing Development Properties and Soil Solidifying Method Using the Same
The present invention relates to a self-healing and eco-friendly soil solidifier powder composition which minimizes heavy metal elution effects by minimizing the use of cement and enhances watertightness and a water-blocking property by being given a self-healing property and a soft ground stabilization method using the same in a preferable manner. The self-healing and eco-friendly soil solidifier powder composition according to the present invention contains 5 to 40 wt% of cement, 10 to 25 wt% of pozzolan reactant, 30 to 75 wt% of blast furnace slag fine powder, 2 to 15 wt% of rapid-hardening material, 2 to 7 wt% of absorbent expansive agent, 1 to 6 wt% of initial rapid-hardening material, and 4 to 10 wt% of self-healing admixture. The rapid-hardening material is calcium sulfur aluminate. The initial rapid-hardening material is an amorphous calcium aluminate compound. The self-healing admixture contains a water-soluble inorganic gelling agent, alkali sulfate, sodium aluminate, and silica. According to the soft ground stabilization method of the present invention, the self-healing and eco-friendly soil solidifier powder composition is injected into soft ground and stirred in a powder state and during the use of compressive air or is injected into soft ground and stirred in a state of slurry mixed with water.
본 발명은 시멘트 사용량을 최소화하여 중금속 용출 영향을 극소화함과 동시에 자기치유특성을 부여하여 수밀성과 차수특성을 증대시킨 자기치유형 친환경 토양 고화재 분체 조성물과 이를 바람직하게 이영한 연약지반 안정화공법에 관한 것이다.본 발명에 따른 자기치유형 친환경 토양 고화재 분체 조성물은, 시멘트 5~40중량%, 포졸란반응물질 10~25중량%, 고로슬래그 미분말 30~75중량%, 속경재 2~15중량%, 흡수팽창재 2~7중량%, 초기급결재 1~6중량%, 자기치유 혼화재 4~10중량%;를 포함하여 조성되되, 속경재는 칼슘설포알루미네이트(Calcium Sulfur Aluminate)이며, 초기급결재는 비정질의 칼슘알루미네이트 화합물이며, 자기치유 혼화재는 수용성 무기질계 겔화재; 알카리 설페이트; 알루민산나트륨; 실리카;를 포함하여 구성된 것임을 특징으로 한다.본 발명에 따른 연약지반 안정화공법은, 자기치유형 친환경 토양 고화재 분체 조성물을 분체 상태로 압축공기를 사용하면서 연약지반에 주입하여 교반하거나, 물과 혼합한 슬러리 상태로 연약지반에 주입하여 교반하는 것을 특징으로 한다.
