초록

본 연구에서는 콘크리트의 내구수명 개선을 위한 친환경 수지인 UM수지 화합물을 혼합한 시멘트 모르타르의 특성을 연구하였다. 친환경수지인 UM수지를 일반 시멘트 모르타르와 일정비율로 혼합하였다. UM수지를 혼합한 폴리머 시멘트 모르타르에 대하여 압축강도, 쪼갬인장강도, 휨강도, 흡수율 및 내약품성 실험을 수행하였다. 재료실험결과 친환경 수지인 UM수지를 함유한 시멘트 모르타르는 압축강도와 쪼갬인장강도는 감소하는 반면 휨강도와 흡수율 및 내약품성에서는 성능이 개선되었다. 친환경 UM수지 폴리머 시멘트 모르타르는 콘크리트 내구성 보강성능이 우수하였다.

In this study, the characteristics of polymer-modified mortar which include UM resin, eco-friendly resin, was studied for improving the durability of concrete. UM and cement mortar were mixed with a certain percentage. Eco-friendly UM resin polymer-modified mortar was evaluated by compressive strength, splitting tensile strength, flexural strength, water absorption and chemical resistance experiments. The characteristics of eco-friendly UM resin polymer-modified mortar were evaluated by experiments. Performance of compressive strength and splitting tensile strength were decreasing. On the other hand, performance of flexural strength, water absorption and chemical resistance were increasing. Eco-friendly UM resin polymer-modified mortar reinforced concrete durability performance is excellent.
