Fig. 7From: Chloride Penetration in Circular Concrete ColumnsRatio of the chloride concentration at depth x or \( \rho_{1} \) from the external exposed surface C and the chloride concentration on the external surface C 0 as function of time of exposure to chloride t. Value extimated for slab model and circula model characterized by radii in the range (20–150 cm).Back to article page
