Abstract

This research is a comparative analysis of the surface gloss of concrete depending on the coating material added to the cast, and includes analyses of the surface gloss of specimens made of cement mortar, with and without the addition of superplasticizer. In terms of coating material, the 7th material, which is part of a liquid packaging material, was shown to have the highest gloss, and was followed by the 3rd material, which uses transparent film. As the level of gloss is shown to vary depending on the material used for the coating film, it can be interpreted that the surface gloss can differ depending on surface particles and chemical composition factors. To make a concrete surface smooth, it is more effective to use a coating material with impermeability and a highly dense surface.

본 연구는 거푸집에 부착하는 코팅재료에 따른 콘크리트 표면광택도 비교 분석으로서 시멘트모르터로 제작한 시험체의 광택도를 분석하고 유동화제를 혼합한 콘크리트와 혼합하지 않은 콘크리트의 노출콘크리트 표면 광택의 특성을 분석한 것이다. 시멘트모르터를 이용한 코팅재료별 광택도 분석에서 광택도가 가장 높게 나타난 코팅재료는 7번 재료로 액체포장재의 일부이며 2번째는 3번 재료로 투명필름을 이용한 재료이다. 코팅필름의 소재에 따라 광택도가 다르게 나타난 것으로 미루어 소재의 표면입자 상태와 화학적 구성요소의 따라 다른 것으로 판단된다. 콘크리트의 표면상태를 매끄럽게 하기 위해서는 불투수성이며 매우 밀실한 표면을 가진 코팅재료를 사용하는 것이 효과적이다.
