FLUIDIZING FILLER COMPOSITION USING CIRCULATING RESOURCES
The present invention relates to a fluidizing filler composition using circulating resources. The fluidizing filler composition of the present invention is a lightweight, low strength and non-contract fluidizing filler composition comprising, as a binder, 15-1,000 parts by weight of blast furnace slag micro powder and 15-1,000 parts by weight of one kind of cement, based on 100 parts by weight of steelmaking process dust containing content of 30-50 wt% of Na_2O and 30-50 wt% of SO_3 generated during desulfurizing processes in a steel mill and as a lightweight aggregate, 5-5,000 parts by weight of any one or in a mixture of waste insulation materials selected from expanded perlite or expanded vermiculite and crushed to have a particle size of 10 mm or less. The binder and aggregate are replaced and used as circulating resources and serve as self-compacting and high fluidized filler, and quick hardening is possible after filling the same into an empty space as a back filler of a structure and pipes and filler for grounds, closed stone quarry, closed mine, and closed pipes, and weight reduction, re-excavation and volume stabilization are possible.
본 발명은 순환자원을 이용한 유동화 채움재 조성물에 관한 것이다. 본 발명의 유동화 채움재 조성물은 결합재로서 제철소 탈황 공정 중에 발생되는 Na2O 함량이 30∼50중량%, SO3 함량이 30∼50중량%인 제철 공정 분진 100중량부에 대하여, 고로슬래그 미분말 15∼1,000중량부 및 1종 시멘트 15∼1,000중량부를 포함하며, 경량골재로서 팽창진주암 또는 팽창질석에서 선택된 폐보온단열재를 입경 10mm 이하로 분쇄된 어느 하나 또는 혼합물 형태로 5∼5,000 중량부를 포함한 경량-저강도-무수축 유동화 채움재 조성물로서, 상기 결합재 및 골재가 순환자원으로 대체 이용되면서도 무다짐 고유동 채움재로 가능하고, 구조물 및 관로 뒷채움재용, 지반, 폐석산, 폐광산 및 폐관 채움재용으로 빈 공간에 채워 넣은 후 급속한 경화가 가능하며 하중절감, 재굴착 및 체적 안정성 확보가 가능하다.
