Mortar Composition for Repair-Reinforcement
The present invention relates to a mortar composition that can be applied to repair and reinforce various structures such as agricultural spillways, drains, road ditches, and sewer pipes. The present invention provides a repair/reinforcement mortar composition that includes binder, fine aggregate, and mixing water, has a water-binder ratio of 18 to 20 wt%, and has a water reducing agent added in an amount of 0.2 to 0.5 wt% compared to the binder. The binder and fine aggregate are mixed at a weight ratio of 1:0.8 to 1.4, wherein 30 to 50 wt% of calcium carbonate compared to the binder is applied to replace the same weight of the fine aggregate, and 0.2 to 0.5 wt% of inorganic acid is added compared to the above calcium carbonate.
본 발명은 농업용 여수로, 배수로, 도로 측구, 하수관거 등 다양한 구조물의 보수·보강에 적용될 수 있는 모르타르 조성물에 관한 것이다. 본 발명은 「결합재, 잔골재 및 배합수를 포함하고, 물-결합재비 18~20 wt%이며, 감수제가 상기 결합재 대비 0.2~0.5 wt% 첨가된 모르타르 조성물로서, 상기 결합재와 잔골재가 1:0.8~1.4의 중량비로 혼합되되, 상기 결합재 대비 30~50 wt%의 탄산칼슘이 상기 잔골재의 동 중량을 대체하도록 적용되고, 무기산이 상기 탄산칼슘 대비 0.2~0.5 wt% 첨가된 것을 특징으로 하는 보수·보강 모르타르 조성물」을 제공한다.
