Heavy-weight mortar composition for flooring with material separation resistance
본 발명은 제지애시, 제강분진 등의 산업부산물을 이용하여, 감수제 증가 또는 단위수량 감소 없이 중량 골재 사용에 의한 재료분리 문제를 해소하는, 재료분리 저항성을 갖는 바닥용 중량 모르타르 조성물에 관한 것이다. 본 발명은 「결합재 30~45 wt; 및 중량 잔골재 55~70 wt%; 를 포함하여 조성되고, 감수제가 상기 결합재 대비 0.3~2 wt% 외할 첨가되되, 상기 결합재는 시멘트 400 중량부; 석고 80~100 중량부; 입경 300㎛ 이하 제지애시 100~150 중량부 및 석회석 미분말 100~130 중량부를 포함하며, 블리딩율 2% 이하, 경화 후 단위중량이 2,300 kg/㎥ 이상인 것을 특징으로 하는 재료분리 저항성을 갖는 바닥용 중량 모르타르 조성물」을 제공한다.
The present invention relates to a heavy-weight mortar composition for flooring with material separation resistance, which uses industrial by-products such as paper ash, steel dust, etc. to solve the problem of material separation caused by the use of heavy aggregate without increasing a water reducing agent or reducing unit quantity. The heavy-weight mortar composition for flooring with material separation resistance of the present invention comprises 30 to 45 wt% of a binder, and 55 to 70 wt% of a heavy fine aggregate, and is added with a water reducing agent in an amount of 0.3 to 2 wt% compared to the binder. The binder includes 400 parts by weight of cement, 80 to 100 parts by weight of gypsum, 100 to 120 parts by weight of paper ash with a particle size of 300 ㎛ or less, and 100 to 130 parts by weight of limestone fine powder. The heavy-weight mortar composition for flooring with material separation resistance has a bleeding rate of 2 % or less and a unit weight after curing of 2,300 kg/㎥ or more.
