Mortar composition with ferronickel slag aggregate and Blast furnance slag fine powder
The present invention relates to an environmentally friendly mortar composition which uses ferronickel slag, which has been discarded as an industrial by-product, as a fine aggregate and blast furnace slag fine powder as a binder. The mortar composition of the present invention comprises: a binder which is mixed with 40 to 80 wt% of cement (OPC) and 20 to 60 wt% of blast furnace slag fine powder (BFSP); and a composite fine aggregate which is mixed with 40 to 60 wt% of ordinary sand (NFA) and 40 to 60 wt% of ferronickel slag fine aggregate (FSA). The assembly ratio of the composite fine aggregate is 2.5 to 3.8.
본 발명은 산업부산물로 폐기되어 온 페로니켈슬래그를 잔골재로 활용하면서 고로슬래그 미분말을 결합재로 함께 사용하는 환경친화적 모르타르 조성물에 관한 것이다. 본 발명은 「시멘트(OPC) 40~80 wt%, 고로슬래그 미분말(BFSP) 20~60 wt%가 혼합된 결합재; 및 일반모래(NFA) 40~60 wt%, 페로니켈슬래그 잔골재(FSA) 40~60 wt%가 혼합된 복합 잔골재; 를 포함하며, 상기 복합 잔골재의 조립율이 2.5~3.8인 것을 특징으로 하는 모르타르 조성물」을 제공한다.
