SOIL GROUTING MATERIAL AND GROUTION METHOD USING THE SAME
The present invention relates to a ground grouting material and a ground grouting construction method, and more specifically, to a ground grouting material obtained by complexly utilizing circulating resources such as waste shells and by-products of steel mills in order to reduce the usage of Portland cement used as a grout material in most ground reinforcement works, and to a grouting construction method using the same. The ground grouting material according to the present invention comprises: 10 to 1,000 parts by weight of fine blast furnace slag powder with a specific surface area of 3,500 cm^2/g or more; 10 to 1,000 parts by weight of sodium bicarbonate desulfurization dust generated as by-products in a desulfurization process of steel mills; and 0.5 to 500 parts by weight of Portland cement of the first class with respect to 100 parts by weight of the waste shell powder with a particle size that is adjusted to 0.01 to 10 mm.
본 발명은 지반 그라우트재 및 지반 그라우팅 공법에 관한 것으로서, 보다 상세하게는 대부분의 지반보강 공사에서 그라우트재로 사용되는 1종 포틀랜드 시멘트의 사용량을 감소시키기 위하여 폐패각과 제철소 부산물 등의 순환자원을 복합 활용한 지반 그라우트재 및 이를 이용한 그라우트 공법에 관한 것이다. 본 발명에 의한 지반 그라우트재는 입경이 0.01∼10mm로 조정된 폐패각 분말 100중량부에 대하여, 비표면적 3,500cm2/g 이상인 고로슬래그 미분말 10∼1,000중량부와, 제철소 탈황공정에서 부산물로 발생되는 중탄산나트륨 탈황 분진 10∼1,000중량부와, 1종 포틀랜드 시멘트 0.5∼500중량부를 포함한다.
