The Torrent air-permeability method, coupled with surface moisture measurements by the electrical impedance method, was applied to 25 specimens produced using different cement types, water-to . The “Torrent” permeability test proved to be a suitable method to measure the air-permeability, performing accurate and reproducible measurements on dimension stones with open porosity above 2 %. It is a non-destructive method that can be used in laboratory and on site and can be applied as complementary or as an alternative method to the .Torrent Permeability Tester Model No – MI- NCT-0239. The permeability of concrete at the surface (concrete cover) has been recognized as a major factor in determining the durability of concrete structures. Many specialists emphasize .
There are two standardized test methods with potential as surrogate tests, as they are fast and entirely nondestructive: the coefficient of air permeability kT (“Torrent” method) and the .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. Mesh and pressure distribution of Torrent's device and concrete for the permeability test by vacuum technique: (a) at the end of the period of vacuum (60 s), (b) at the end of the period of measurement (330 s after the end of the vacuum in the central cell) for concrete C2 at 30 % of saturation (φ g = 0.1, k ref _ EF = 4.4 × 10 − 17 m 2, b .The Torrent permeability tester permits a rapid and non destructive measurement of the quality of the cover concrete with respect to its durability.
