Eco Mortar Composition having Copper Slag Powder and Recycled Fine Aggregates
The present invention relates to a mortar composition for manufacturing recycled aggregate concrete in which recycled fine aggregate and copper slag fine powder are mixed. According to the present invention, the mortar composition is manufactured by using copper slag fine powder with a particle size of 1.2 mm or less, which has been discarded as an industrial by-product, together with recycled fine aggregate, so that re-reaction (hardening) of the recycled fine aggregate is prevented and concrete exhibits sufficient strength through effects of increasing the density of recycled fine aggregate and lowering absorption rate while providing excellent fluidity and workability of recycled aggregate concrete, thereby being used for a variety of purposes. The mortar composition comprises cement, water, an expansive admixture, an AE agent, natural fine aggregate, recycled fine aggregate, and copper slag fine powder.
본 발명은 산업부산물로서 폐기되던 입경 1.2㎜ 이하의 동슬래그 미분말을 순환 잔골재와 함께 사용하여 모르타르 조성물을 만들므로써, 순환 잔골재의 재반응(경화)을 방지함과 동시에 순환골재 콘크리트의 우수한 유동성 및 워커빌러티(workability/작업성)를 가지면서도, 순환 잔골재의 밀도 증가 및 흡수율 저하 효과를 통해서 콘크리트가 충분한 강도를 발휘할 수 있게 만들어서 다양한 용도로 사용할 수 있게 되는 "순환 잔골재 및 동슬래그 미분말을 혼합한 순환골재 콘크리트 제조용 모르타르 조성물"에 관한 것이다.
