Zusammenfassung:	The present invention relates to fine aggregate for concrete, including mixed slag in which ferronickel slag and blast furnace slag are mixed to compensate for the defects of ferronickel slag and blast furnace slag. According to the present invention, provided is fine aggregate for concrete, comprising mixed slag in which ferronickel slag and blast furnace slag are mixed. The mixed slag fine aggregate according to the present invention exhibits improved fluidity and/or strength when applied to concrete and/or mortar as a sand substitute. In addition, the mixed slag fine aggregate of the present invention exhibits improved shrinkage. In addition, the problem of unbalanced supply and demand of natural aggregate can be solved, and the effect can be expected as a method of recycling slag as valuable resources. 본 발명은 페로니켈슬래그와 고로슬래그의 결함을 보완한 페로니켈슬래그와 고로슬래그가 혼합된 혼합슬래그를 포함하는 콘크리트용 잔골재에 관한 것이다. 본 발명에 의하면, 페로니켈슬래그 및 고로슬래그가 혼합된 혼합슬래그를 포함하는 콘크리트용 잔골재가 제공된다. 본 발명에 의한 혼합슬래그 잔골재는 모래 대체재로 콘크리트 및/또는 모르타르에 적용시, 향상된 유동성 및/또는 강도를 나타낸다. 뿐만 아니라, 본 발명의 혼합슬래그 잔골재는 개선된 수축률을 나타낸다. 또한, 천연골재 수급 불균형 문제를 해결할 수 있고 슬래그를 유가자원으로 재활용하는 방안으로서 그 효과를 기대할 수 있다.
