Chloride Penetration in Circular Concrete Columns

The chloride penetration in the concrete matrix occurs through either permeation and absorbition of a chloride solution or diffusion of free chloride ions into the saturated concrete (Val and Trapper 2008; Martin-Perez et al. 2001). These mechanisms may also occur sequentially. The absorption runs out in short time and after that the diffusion
