Abstract
Torrent air permeability tester has been widely used as one the most reliable non-destructive tests for evaluating the quality of the concrete cover. In this study, the Torrent tester was employed to evaluate the influence of rebar con-finement on the surface layer quality of expansive concrete. Blast furnace slag cement was used with the expansive agent to prepare two types of specimens with/without embedded rebars. The results comparing the variation of the measured air permeability at the ages of 28 and 56 days indicated that the con-crete cover confined by rebars obtained a better quality than that of the plain one without rebars.
