| Abstract |
The durability of concrete is significantly dependent on its ability to withstand aggressive environmental condition, particularly against the attack of chloride in marine environment. Various factors... of the fresh property of concrete require accurate understanding to prevent its precocious deterioration. Bleeding of water is a common phenomenon occurring in fresh concrete, promoting the surge of voids along to the lower surface of horizontal steel bars. However, studies are still required for better handling of the phenomenon and its effects. This study is aimed at examining the influence of the interfacial gap caused by bleeding water and chloride content on the corrosion of reinforcing steel using non-destructive electrochemical tests and visual observations. The results suggest that the steel bar position is a factor affecting the concrete corrosion due to the increase of the void. It has been shown that the void on the undersurface of the rebar are more significant in the upper section of the structure leading to a more severe corrosion in those areas.show more
