MOLTAL AGENT AND COMPACTION GROUTING METHOD THEREBY
The present invention relates to: a dry mortar composition for a consolidation grouting method which allows a bottom ash discharged from the bottom of a circulating fluidized bed boiler, which is a low utilization industrial by-product, to simultaneously play the role of a stimulator and aggregate of a blast furnace slag micropowder, thereby replacing raw materials that must be obtained by damaging natural resources with circulating resources; and the consolidation grouting method using the same. The dry mortar composition for the consolidation grouting method according to the present invention, based on 100 parts by weight of a circulating fluidized bed boiler bottom ash adjusted to have a particle size of 0.01 to 5 mm, contains 5 to 100 parts by weight of the blast furnace slag micropowder and 1 to 30 parts by weight of cement.
본 발명은 활용도가 낮은 산업 부산물인 순환 유동층 보일러 하부에서 배출되는 바텀애시를 고로슬래그 미분말의 자극제와 골재로서 동시 역할을 수행하게 함으로서 천연자원을 훼손하여 얻어야만 하는 원재료를 순환자원으로 대체할 수 있는 압밀 그라우팅 공법용 건조 모르타르 조성물 및 이를 이용한 압밀 그라우팅 공법에 관한 것이다. 본 발명에 의한 압밀 그라우팅 공법용 건조 모르타르 조성물은 0.01∼5mm의 입도를 갖도록 입도조정된 순환 유동층 보일러 바텀애시 100중량부에 대하여, 고로슬래그 미분말 5∼100중량부와, 시멘트 1∼30중량부를 포함하는 것을 특징으로 한다.
