The permeability of concrete plays an important role in the long-term performance and durability of this material while exposed to aggressive environments. Even in the case of internal damaging mechanisms such as alkali-aggregate reaction, low permeability resulting in low permeability, in impeding the rate of damage propagation. Various methods have been utilized to assess concrete permeability such as water absorption, gas permeability, and electrical resistivity measurement. However, the most commonly used standard method in various countries is rapid chloride permeability test (RCPT). Perma2 is a completely re-engineered laboratory test device for the measurement of the electrical resistance of concrete against the penetration of chloride.

“Giatec Perma is a great unit, simple to setup and use. Very quiet and safe. Small footprint, requires very little bench space.” Mr. Gordon Chan, Technician at Constriction Portfolio, National Research Council of Canada. 

The test setup is easy to assemble and the stand-alone device facilitates the measurements to be made conveniently. Please click here to watch a quick tutorial video on how the RCPT method works.

Rapid Chloride Permeability Test method has been adopted by many standard organizations and building codes worldwide. For example, ASTM C1202, AASHTO T277CSA A23.1 provide the detailed procedure for sample preparation, conditioning and testing.
