The present invention relates to a cement-based grouting composition, wherein the cement-based grouting composition is formed by mixing a curing agent obtained by mixing 190 to 230 kg of a cement composite, 22 to 28 kg of an admixture, and 400 to 440 L of water with an accelerating agent formed of a silica sol acid solution in a weight ratio of 1:1, the cement composite is a mixture of cement and a composite in a weight ratio of 5:5 to 6:4, the composite includes 65 to 75 wt% of silicate, 22 to 28 wt% of fly ash, and 3 to 7 wt% of a polycarboxylic acid-based compound, the admixture includes 60 to 70 wt% of quicklime and 30 to 40 wt% of silica, and the silica sol acid solution includes 30 to 34 wt% of sodium silicate, 60 to 66 wt% of water, and 3 to 7 wt% of a 90% sulfuric acid aqueous solution. Accordingly, workability is improved.
본 발명은 시멘트 복합제 190~230kg, 혼화제 22~28kg, 물 400~440ℓ의 비율로 혼합되는 경화제와 실리카졸 산성액으로 되는 급결제를 1:1의 중량 비율로 혼합하여서 되되, 상기 시멘트 복합제는 시멘트와 복합제를 5:5~6:4의 중량 비율로 혼합한 것으로, 상기 복합제는 실리케이트 65~75중량%, 플라이애시 22~28중량%, 폴리카르본산계 화합물 3~7중량 %이고, 상기 혼화제는 생석회 60~70중량%, 실리카 30~40중량%이고, 상기 실리카졸 산성액은 규산소다 30~34중량%, 물 60~66중량%, 90%비율의 황산수용액 3~7중량%로 되는 시멘트계 그라우팅 조성물에 관한 것이다.
