Eco-friendly mortar composition with blast furnace slag fine aggregate and ready-mixed concrete recovered water
The present invention relates to an eco-friendly mortar composition applied with blast furnace slag fine aggregate generated as an industrial by-product after metal is removed from ore in a steelmaking process and ready-mixed concrete recovered water generated during the preparation of ready-mixed concrete, wherein the recycling rate of recovered water, which is a by-product of the ready-mixed concrete industry, is increased. More specifically, the present invention relates to a method for promoting fluidity, strength and durability by increasing the mixing ratio of blast furnace slag fine aggregate in mortar using general Portland cement and natural mountain sand fine aggregate. The present invention provides an eco-friendly mortar composition to which blast furnace slag fine aggregate and ready-mixed concrete recovered water are applied, wherein the composition includes: 330 to 360 parts by weight of cement; 80 to 320 parts by weight of fine aggregate; and 160 to 180 parts by weight of mixing water. The fine aggregate is composed of 60 to 90 vol% of natural fine aggregate and 10 to 40 vol% of blast furnace slag fine aggregate. The mixing water contains 5.0 to 10.0 wt% of solids obtained from the recovered water of ready-mixed concrete. The solids promote the reactivity of the blast furnace slag fine aggregate.
본 발명은 레미콘산업 부산물인 회수수의 재활용율을 증대시키고 제철 과정에서 광석으로 부터 금속을 빼내고 산업부산물로 발생되는 고로슬래그 잔골재와 레미콘 제조 과정에서 발생되는 레미콘회수수를 적용한 친환경 모르타르 조성물에 관한 것이다. 보다 상세하게는 일반 포틀랜드 시멘트와 천연 산모래 잔골재가 사용된 모르타르에 고로슬래그 잔골재 혼입율을 증가시킴으로서 이의 유동성, 강도 및 내구성능을 촉진시키기 위한 방법이다. 본 발명은 「시멘트 330~360중량부; 잔골재 80~320중량부; 및 배합수 160~180중량부; 를 포함하되, 상기 잔골재는 천연 잔골재 60~90vol% 및 고로슬래그 잔골재 10~40vol%로 조성되고, 상기 배합수는 레미콘회수수에서 수득한 고형물이 5.0~10.0wt% 포함되어, 상기 고형물이 상기 고로슬래그 잔골재의 반응성을 촉진시키는 것을 특징으로 하는, 고로슬래그 잔골재 및 레미콘회수수가 적용된 친환경 모르타르 조성물」을 제공한다.
