Some dolomite aggregates exposed to a wet environment may decompose. The presence of sodium, magnesium, calcium and sulfate ions in the corrosive medium and the higher temperature can increase the rate of aggregate decomposition. The results of a study on the impact of defined environmental exposition to a H2O, Mg(OH)(2), MgSO4, Na2SO4 solutions in various temperature conditions on the susceptibility to dedolomitisation processes of cement concrete made with selected dolomite aggregate are presented in the paper. The observation of linear extension as well as changes in compressive strength and surface alteration due to corrosive exposition conditions were the key diagnostic features adopted for this examination.
