Portland cement CEM I 52-5N was used. Two different corrosion inhibitors were selected within this study. One was a calcium nitrite-based corrosion inhibitor, which contained minimum 30 % active ingredients by mass. The other corrosion inhibitor was an aqueous mixture of amine and ester. By means of mercury intrusion porosimetry it was shown that for each degree of cement hydration considered in the experimental programme, the cement paste with inhibitor had higher total pore volume than the reference cement paste.
