An Analysis on the Early Frost Damage According to the Component Thickness Changes of the Normal Strength Concrete Slab in Winter

겨울철 보통강도 콘크리트의 부재 두께 변화에 따른 초기동해 피해분석

In this study, the purpose of the study is to determine the depth of damage caused by early frost damage in concrete slab structures under the conditions of external temperature during winter. In other words, we intend to analyze the depth variation of the early frost damage as the thickness of the normal strength concrete slab members changes. As a result, the thinner the component was, the deeper the early frost damage was found to be, and the resulting increase in brightness of the concrete was delayed. and It is analyzed that under this test condition, an early frost damage was created with a thickness of 50 mm for the member and a thickness of 39 mm for the member of 300 mm.
