Fig. 10From: Chloride Penetration in Circular Concrete ColumnsThe ratio of chloride concentration at the depth of steel bars in the concrete matrix C and the threshold chloride concentration \( C_{cr} \) as function of the exposure time t. Calculation made for chloride concentrations on the external surface C 0 = [0.25, 0.30, 0.35 %] and radii of the circular cross section R = [30, 50, 100 cm].Back to article page
