Recently, a lot of buildings are constructed near marine environment because many people prefer to the excellent landscape and the good view. therefore, it is increased the damage as a chloride from the sea. For this reason, many researches of chloride ion penetration have been conducted but there is no study about the effect of aggregate in concrete. So, the purpose of this study are predicting the chloride ion diffusion coefficient and life of concrete by the properties of aggregate. In this experiment, the effect on chloride ion diffusion coefficient and the durability of concrete were investigated along with the change of grading and s/a of aggregate. As the result, the effect of the properties of aggregate on chloride ion diffusion coefficient and the durability of concrete are too little to evaluate it. And diffusion coefficient in steady state was evaluated as low as 1/10 of that in non-steady state. In the future, this study need to estimate the effect of aggregate on chloride diffusion coefficient at high-strength concrete. |
