Basic study on selecting mold transfer paper for gloss exposed mass concrete

광택 노출콘크리트용 거푸집 전사지 선정에 관한 기초적 연구

Ways to efficiently manufacture gloss exposed mass concrete at an inexpensive price, in other words, ways to paste transparent transfer paper onto the surface of a combined mold has been designated as New Technology Article 191 by the Ministry of Land, Infrastructure and Transport. But if the difference in the coefficient of linear expansion between the mold's and transfer paper's material causes temperature to rise or fall, a wrinkly surface can appear. Therefore this study, by experimentally comparing the deformation characteristics between the mold material and transfer paper material upon changes in temperature, seeks to serve as a basic reference point for selecting the optimal transfer paper for different mold types. Study results revealed that for molds, polyester resin transfer paper is optimal, and for aluminum molds, acrylic resin transfer paper is.
