Positron annihilation lifetime measurements have been conducted on mature cement pastes, subjected to drying and rewetting treatments that remove and restore the free water from the pastes, to study possible changes of the microstructure, Analysis of the results suggests that repeated drying followed bg rewetting does not induce irreversible modifications in the configuration of the finest gel pores.
