Abstract1   철근 콘크리트 건물의 외부 마감은 건물의 외부 디자인뿐만 아니라 외부의 온도, 눈, 바람, 비와 같은 자연 환경 또는 재난을 방지하고 내구성을 방지하는 중요한 요소 중 하나이다. 따라서 본 논문에서는 기존 방법의 문제점을 극복하기 위해 금속공법 적용해 표면거칠기에 따른 부착강도를 평가 하였다. 실험 결과 샌드블라스트+조면형성제 도포한경우 약 3.19MPa 로 가장 우수한 부착강도를 나타내었다.
Abstract2   The exterior finishing of reinforced concrete buildings is one of the important factors to prevent durability and prevent natural environment or disaster such as temperature, snow, wind, rain from the outside as well as external design of buildings. Finishing methods can be divided into wet and dry methods. The wet method using paint is relatively easy to construct, but it requires repair and reinforcement every 1 to 5 years and requires a lot of LCC for maintenance. Finishing method using panel has good durability, but it is difficult to install and expensive. Therefore, in this paper, we evaluate the bond strength for the application of the metal spray method in order to overcome the problems of existing methods. Experimental results show that the sandblast + surface roughness agent(S-R(Y)) has a roughness of 41.16 ㎛ and the bond strength is about 3.19 MPa, which is the highest bond strength. In addition, the grinding + surface roughness agent(G-R(Y)) application showed roughness of about 36.59 ㎛ and secured the bond strength performance of 2.94 MPa.
