Abstract:
In an effort to show correlation of soluble alkalies with alkali-aggregate reaction, the authors hydrate a number of cement for periods up to 90 days and analyzed water extracts of the ground, hydrated cement. However, the correlation with expansions of mortar bars prepared with reactive aggregate was not improved by considering water-soluble alkalies rather than total alkalies. The rate at which the alkalies become water-soluble in hydrating cement indicates that the alkali-bearing phases in cement hydrate quite readily.
