Torrent Permeability Test

มาตรฐาน


The following standards can be applied to the
permeability tester:

 

  • SN 505 252/1, Annex E

รายละเอียด

The permeability of concrete at the surface is a major factor in determining
the durability of concrete structures. A reliable permeability test of the concrete
cover is therefore crucial – not only in the laboratory but also at the building site.
One factor determining the durability of concrete is the ease with which air can
penetrate into concrete.

The permeability test with the Torrent permits a rapid analysis of the air
permeability of the cover concrete by a non destructive method. The essential
features of the permeability test method of the Torrent are a two-chamber
vacuum cell and a pressure regulator which ensures an air flow at right angles
to the surface into the inner chamber. The permeability test with the Torrent
takes only 2 – 12 minutes.
 

•The data is automatically collected by the Torrente permeability tester
•The quality class of the concrete cover of dry concrete can be read
  from a table using the kT value
•In the case of moist concrete, kT is combined with electrical concrete
  resistance ρ (rho) and the quality class is determined from a nomogram
•Optional resistance Wenner-probe to correct the influence of concrete
  moisture is available with the permeability tester.
