✦ Synopsis

It has been shown that the same quantity of C1-added to ordinary Portland cement mortar as CaCl 2, NaCI or KCI has an effect on the corrosion rate which is strongly dependent on the cation, CaCI 2 having a much more deleterious effect than either NaCI or KCI. This effect is shown to be due to a combination of a coarsening of the pore structure and a decrease in the pH of the pore solution by the CaCI2, but is not related to concentration of chloride ions remaining in the pore solution.
