Özet
This study investigates the sea water and ammonium nitrate resistance of cement mortars when subjected to different exposure conditions. Cement mortar samples were prepared using Boron, CEM I and CEM III/A cements. Mortar specimens were stored under three different conditions: continuous curing in lime-saturated tab water, continuous exposure to sea water, and continuous exposure to 5% ammonium nitrate solution (AN), at a temperature of 20 +/- 3 degrees C, for 2, 7, 14, 28 and 90 days. Prisms with dimensions of 25x25x285 mm, to determine the expansions of the mortar samples; and another set of prisms with dimensions of 40x40x160 mm, were prepared to calculate the compressive strength of the samples. For all environmental conditions and ages, the lowest expansion is found for CEM III/A cement mortars. It has been observed that CEM III/A cement mortars have the highest resistance for both sea water and environments with ammonium nitrate.
