Analysis of Chemically Resistant Characteristic to the Liquid-Applied Membrane Waterproofing Materials of the Rapidly Hardening Sprayed Type Applied on the Concrete Structure

콘크리트 구조물에 적용되는 초속경 분사시공 도막 방수재료의 내화학 특성 분석 - 폴리우레아, 폴리우레탄.우레아, 폴리우레탄 수지계 방수재료를 중심으로 -

In this study, the chemical resistance of polyurea resin waterproofing and anti-corrosion materials that is applied to the social infrastructure was analyzed. The chemical performances were realized by the validation test for understanding as detailed point of view to the characteristics of the polyurea waterproofing and anti-corrosion Among the specimens that are the polyurea resin waterproofing and anti-corrosion, polyurea resin waterproofing and anti-corrosion, polyurethan-polyurea waterproofing and anti-corrosion, and polyurethane waterproofing and anti-corrosion were analyzed as the specimen. As a result of chemically resistant characteristic to three kinds of polyure type materials, it's polyurethane, polyurea-urethane, and polyurea were arranged in the order. This order is generally predictable order that is expected by any user, but it was settled first by the quantitative evidence of chemical evaluation in this time. And, the result in this study will be utilizing as a basic data for establishing the quality standards which are able to judge the chemically resistant characteristic of polyurea resin waterproofing and anti-corrosion materials.
