HIGH EARLY STRENGTH REPAIR MATERIALS COMPOSITIONS FOR CONCRETE BRIDGE DECK AND REPAIRING METHOD FOR CONCRETE BRIDGE DECK USING THAT
The present invention relates to an ultra-rapid hardening repair material composition for a bridge deck, which comprises the following: an A part comprising a resinous MMA polymer which has a methyl methacrylate structure and an unsaturated polyester structure; and a B part forming a repair material by being mixed with the A part, formed into a ceramic powder form so as to be cured within a predetermined time after mixing, and composed of calcium carbonate, microsilica, high-strength silica 6, high-strength silica 5, an inorganic thickener, and a curing initiator.
본 발명은, 메타크릴산메틸(Methyl Methacrylate) 구조와 불포화 폴리에스테르 구조를 구비하는 수지상의 MMA폴리머를 포함하는 A부; 및 상기 A부와 혼합되어 보수재를 이루고, 혼합된 후에 설정 시간 내에 경화되도록 세라믹 파우더 형태로 이루어지며, 탄산칼슘, 마이크로 실리카, 고강도 규사6호, 고강도 규사5호, 무기질 증점제 및 경화개시제를 포함하여 이루어지는 B부를 포함하는 것을 특징으로 한다.
