Effect of Storage on Air-Entraining Cements

Source

This subject is introduced by reference to a previous study of the effect of storage on the properties of portland cement. Results of tests on samples of types I, IA, IIA, and IIIA portland cement stored under various conditions for periods up to 5 yr are reported. The effect of time and condition of storage on air content, ignition loss, specific surface, and free lime results was determined at intervals during the 5-yr period. These tests show that aging of cement does not cause any significant change in the above properties, or the setting time, or compressive strength if the cement is properly stored so as to prevent any reaction with moisture or carbon dioxide, as would be shown by no appreciable increase in the ignition loss.
