Rapid Chloride Permeability of Concrete

Ref.: H0379


Perma2™ is a laboratory test device for the measurement of the resistance of concrete against the penetration of chloride (RCPT) according to ASTM C1202, AASHTO T277 and ASTM C1760 standards. The measurement data can be used to estimate the chloride diffusion coefficient of concrete for the service life prediction and durability-based design of concrete structures as well as the durability-based quality control of concrete.

The ASTM C1202 test provides an indication of concrete resistance to the penetration of chloride. The correlations between the results of this test (charged passed) and the long-term chloride penetrability of concrete established by ASTM C1202 are presented in Table 1.

The ASTM C1760 test provides estimation for the bulk electrical conductivity of saturated specimens of hardened concrete. The results reveal a rapid indication (i.e., in one minute) of the concrete’s resistance to the penetration of chloride by diffusion. The results of this test method can be also related to the apparent chloride diffusion coefficient that is determined using ASTM C1556 test method.


Perma2™ device can be used for testing the durability of concrete exposed to chloride-contaminated environment including:

  • Concrete’s ability to resist chloride ion penetration (ASTM C1202, AASHTO T277)
  • Bulk electrical conductivity of concrete (ASTM C1760)
  • Performance-based quality control of concrete
  • Estimation of chloride diffusion coefficient of concrete
  • Estimation of chloride migration coefficient of concrete
  • Service life design of concrete structures
  • Estimation of the remaining life of concrete structures


The followings are unique features of this device:

  • Stand alone operation
  • Easy-to-assemble
  • Auto-sealable cells with rubber gasket and spacer (i.e. does not require caulking)
  • Accurate (±0.1 mA)
  • Flexible logging interval time (1 to 10 min)
  • Automatic temperature control system
  • Four measurement channels
  • User-friendly PC software
  • Customizable setup
  • USB connection to computer
  • Verification kit


The only RCPT device in the market that meets the specifications of ASTM and AASHTO standard for sample cell

Perma2TM has CSA electrical safety certification mark for use in concrete laboratories
