• Portland-pozzolana cement pastes hydrated at 1,2 and 3 days were investigated for permeability tests. They were carried out with distilled water or lime-saturated solutions. Significant differences in flow rates, depending on the period of curing of cement pastes and on the type of testing solution, have been observed. Among the effects that influence the permeation process, an osmotic pressure that originates when distilled water is forced through disk-shaped specimen, has been considered.

Abstract
• Portland-pozzolana cement pastes hydrated at 1,2 and 3 days were investigated for permeability tests. They were carried out with distilled water or lime-saturated solutions. Significant differences in flow rates, depending on the period of curing of cement pastes and on the type of testing solution, have been observed. Among the effects that influence the permeation process, an osmotic pressure that originates when distilled water is forced through disk-shaped specimen, has been considered.File in questo prodotto:
