New Accelerated Methods for Predicting Durability of Cementitious Materials

Source

Miniature specimens of different configurations have been used to study the durability of cementitious materials. The tests involved monitoring the dimensional change or mechanical property in the following studies under specified rigorous conditions: (a) unsoundness of lime, (b) failure of white coat plasters, (c) unsoundness of cement containing magnesium oxide (MgO) and calcium oxide (CaO), (d) durability of cement mortars exposed to chloride solutions, (e) resistance of sulfur-impregnated cement systems to high humidities, and (f) drying shrinkage of cements with and without admixtures. The results indicate that the tests are not only applicable for the prediction of durability of materials but that they also may be used to study the mechanisms of material deterioration.
