test methods [11–13]. Pertaining to the non-destruc-tive aspect, several permeability assessment methods have been proposed and validated [14–18]. Among these methods, a double vacuum cell test, Torrent’s air-permeability test, was proposed to determine the coefficient of permeability kT and the affected depth [15].The Torrent permeability tester permits a rapid and non destructive measurement of the quality of the cover concrete with respect to its durability. Concrete permeability is an excellent indicator of the potential durability and resistance of a particular concrete against the ingress of aggressive media in the gaseous or liquid state.
test for the air permeability of concrete. With this background, this research used the Torrent method, which has been commercialized as Per-mea-TORR, for measuring the surface air permeability. The coefficient of surface air permeability by the Torrent method (kT) is computed by the following numerical formula (Eq.
