Concrete Section Repair And Reinforcement Method Using Polymer Mortar
The present invention relates to a concrete cross-section repair and reinforcement method using polymer mortar, and, more specifically, to a concrete cross-section repair and reinforcement method using polymer mortar, wherein the polymer mortar includes a mixture of 37 wt% to 44 wt% of Portland cement, 3 wt% to 5 wt% of calcium sulfoaluminate, 49 wt% to 56 wt% of silica sand, 0.3 wt% to 0.5 wt% of naphthalenesulfonic acid, 0.1 wt% to 0.3 wt% of polyvinyl alcohol fiber, 0.7 wt% to 1 wt% of vinyl acetate ethylene polymer, and 0.3 wt% to 0.5 wt% of methyl cellulose, and the concrete cross-section repair and reinforcement method using the polymer mortar comprises: (a) a chipping and cleaning step (S11) in which a damaged portion of a deteriorated concrete structure is chipped and cleaned with high-pressure water to remove foreign substances; (b) a concrete reinforcement agent application step (S12) in which a concrete reinforcement agent is uniformly applied onto the surface of the damaged portion from which the foreign substances have been removed, to fill surface cracks and strengthen the surface; (c) a filling step (S13) in which a cross-section is restored by filling the surface, onto which the concrete reinforcement agent is applied, by applying the polymer mortar by using a hand plastering method; and (d) a surface finishing material application step (S14) of finishing by applying a surface finishing material onto the surface of the cross-section filled with the polymer mortar. According to the present invention, by dramatically reducing the amount of polymer used, material costs are reduced, thereby reducing overall production costs.
본 발명은 폴리머 모르타르를 이용한 콘크리트 단면 보수 보강 공법에 관한 것으로서, 보다 상세하게는 폴리머 모르타르는 포틀랜드 시멘트 37 ~ 44 중량%, 칼슘설포알루미네이트 3 ~ 5 중량%, 실리카 샌드 49 ~ 56 중량%, 나프탈렌설폰산 0.3 ~ 0.5 중량%, 폴리비닐알코올 화이버 0.1 ~ 0.3 중량%, 비닐 아세테이트 에틸렌 폴리머 0.7 ~ 1 중량%, 메틸 셀룰로오스 0.3 ~ 0.5 중량%로 혼합되어 구성되며, 이를 이용한 콘크리트 단면 보수 보강공법은 (a) 열화된 콘크리트 구조물 손상부를 치핑하고 고압수로 세척하여 이물질을 제거하는 치핑 및 세척 단계(S11); (b) 이물질 제거된 손상부 표면에 구체강화제를 균일하게 도포하여 표면 균열을 메우고 강화하는 구체강화제 도포단계(S12); (c) 상기 구체강화제 도포면에 폴리머 모르타르를 손미장등으로 도포하는 방식으로 충전하여 단면을 복구하는 충전단계(S13); 및 (d) 상기 폴리머 모르타르가 충전된 단면의 표면에 표면마감재를 도포하여 마무리하는 표면마감재 도포단계(S14);로 구성됨을 특징으로 하는 폴리머 모르타르를 이용한 콘크리트 단면 보수 보강 공법에 관한 것이다.
