Abstract
Positron annihilation lifetime measurements have been conducted on mature c ement pastes, subjected to drying and rewetting treatments that remove and restore the free water from the pastes, to study possible changes of the mi crostructure, Analysis of the results suggests that repeated drying followe d bg rewetting does not induce irreversible modifications in the configurat ion of the finest gel pores.
