Non-cement Mortar with Reduction of Autogenous Shrinkage And Carbonation
The present invention relates to eco-friendly non-cement mortar in which fly ash and slag, which are industrial by-products, as a binder and calcium carbide sludge is added to the binder, such that self-shrinkage and carbonation resistance can be increased. According to the present invention, self-shrinkage and carbonation-reduced non-cement mortar comprises: a binder including 30 to 40 wt% of slag, 30 to 40 wt% of fly ash, 10 to 30 wt% of red mud, and 10 to 30 wt% of rice husk ash; 5 to 15 parts by weight of calcium carbide sludge mixed with respect to 100 parts by weight of the binder; 150 to 180 parts by weight of aggregate mixed with respect to 100 parts by weight of the binder; and 40 to 45 parts by weight of water mixed with respect to 100 parts by weight of the binder.
본 발명은 산업부산물인 플라이 애시(fly ash)와 슬래그(slag)를 결합재로 사용하고, 여기에 칼슘카바이드 슬러지를 혼입하여 자기수축 및 탄산화 저항성을 향상시킬 수 있는 친환경 무시멘트 모르타르에 관한 것으로, 본 발명에 따른 자기수축 및 탄산화 저감 무시멘트 모르타르는, 슬래그(slag) 30~40 중량%와, 플라이 애시(fly ash) 30~40 중량%, 레드머드(red mud) 10~30 중량%, Rice husk ash 10~30 중량%를 포함하는 결합재와, 상기 결합재 100 중량부에 대해 5~15 중량부로 혼합되는 칼슘카바이드 슬러지와, 상기 결합재 100 중량부에 대해 150~180 중량부로 혼합되는 골재와,상기 결합재 100 중량부에 대해 40~45 중량부로 혼합되는 물을 포함한다.
