Abstract

본 연구는 알루미늄 거푸집 표면코팅재가 콘크리트 표면품질에 미치는 영향에 대하여 분석한 것이다. 콘크리트 표면형상에 미치는 알루미늄 거푸집 표면코팅재 변화의 영향에 따른 콘크리트 표면의 육안관찰시 전반적으로 전용횟수가 증가함에 따라 표면품질은 저하하는 것으로 나타났고, 치장합판(Plywood이하: PW)이 우수한 표면품질을 나타내었다. 에폭시(Epoxy :이하 EP) 수지의 경우는 박리제를 도포하였을 시 표면품질이 우수한 것으로 나타났다. 박리제 도포여부 및 전용횟수에 따른 콘크리트의 표면조도는 전용횟수가 증가함에 따라 가장 높은 표면조도 값을 나타내어 평활성이 불량한 것으로 나타났지만, EP와 PW의 표면조도 값은 가장 우수한 것으로 나타났다. 다만 EP의 경우는 박리제를 도포할 경우 표면조도 값이 낮게 나타났다. 박리제 도포여부 및 전용횟수에 따른 콘크리트의 공극갯수는 전반적으로 박리제를 도포할시 저감하는 것으로 나타났다. This study is to analyze the effects of aluminum form surface coating material on surface quality of concrete. When observing the surface quality of concrete affected by the change of aluminum form surface coating material, in general, as the number of use of the coating material increased, the surface quality of concrete decreased and good surface quality was shown in plywood (hereinafter PW). For epoxy (hereinafter EP) resin, when applying form remover, good surface quality was shown. For the surface roughness of concrete by the application form oil of form remover and the number of use of the coating material, as the number of use increased, highest surface roughness value was shown which meant the leveling was bad, but the surface roughness value in EP and PW was the lowest. Just for EP, when applying form remover, surface roughness value was low. For the number of void for concrete by the application of form remover and the number of use of the coating material, In general, the number of void which was generated when applying form oil the remover decreased.
