Effect of Time-dependancy of Surface Chloride Content on the Time-to-corrosion Initiation in concrete

The initiation of steel corrosion due to chloride diffusion is predicted to consider time-dependancy of surface chloride content. the profile of chloride concentration is the following: constant condition > square root condition > linear condition From these results, the initiation of steel corrosion in concrete is reverse order of above results of chloride profile. the effect of prolongation to initiation of steel corrosion is decreased with increasing concrete cover
