시공시 균열저항성을 갖는 고강도 콘크리트 스페이서 개발

Development of High-Strength Concrete Spacer with Crack Resistance during Construction

Spacers which we studied about is the secondary product of the concrete and it is applied on concrete structure. Therefore, securing equal or greater performance than concrete is desirable. Also, there is a tendency that concrete structures are strengthened. Therefore, reinforcement is used more and it is needed highly strengthened spacer. In this study, therefore, we would like to develop highly strengthened spacer which has crack resistance during construction. After this study, we confirmed that the spacer we developed has good crack resistance in construction.
