Eco-friendly mortar composition with blast furnace slag fine aggregate and ready-mixed concrete recovered water
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.
The present invention relates to an eco-friendly mortar composition, which leads to an increase in recycling rate of recovered water, a by-product in the ready-mixed concrete industry, and employs blast furnace slag fine aggregates generated as an industrial by-product after the extraction of metals from ore during a steelmaking procedure and ready-mixed concrete recovered water generated during a ready-mixed concrete producing procedure. More specifically, the present invention relates to a method in which blast furnace slag fine aggregates are incorporated at an increased ratio into mortar employing ordinary Portland cement and natural pit sad fine aggregates, thereby promoting the fluidity, strength, and durability performance of the mortar. The present invention provides an eco-friendly mortar composition employing blast furnace slag fine aggregates and ready-mixed concrete recovered water, the mortar composition comprising 330-360 parts by weight of cement, 80-320 parts by weight of fine aggregates, and 160-180 parts by weight of combined water, wherein: the fine aggregates are composed of 60-90 vol% of natural fine aggregates and 10-40 vol% of blast furnace slag fine aggregates; the combined water contains 5.0-10,0 wt% of solids obtained from ready-mixed concrete recovered water, the solids promoting the reactivity of the blast furnace slag fine aggregates.
