Abstract
Portland cement-based materials exhibit water absorption anomaly that is due to the swelling associated with the hydration and rehydration of unreacted and dehydrated components of hardened cement paste. Permeability and long term capillary absorption tests further supports these observations. Short and long term capillary absorption properties observed on mortars and concrete made of Portland cement partially replaced with ground granulated blast-furnace slags show smaller differences between water and organic liquid absorption. As the blend contains less of the low-density calcium silicate hydrate gel which is the component involved in shrinkage and swelling in the presence of water, these results are also consistent with the swelling hypothesis.
