Perma2

Giatec Perma2™ is a completely re-engineered laboratory test device for the measurement of the electrical resistance of concrete against the penetration of chloride (RCPT) according to the standard methods such as ASTM C1202, AASHTO T277 and ASTM C1760. The measurement data can be used to estimate the chloride diffusion coefficient of concrete for the service life prediction and design of concrete structures as well as the durability-based quality control of concrete. Perma2™ is electrically certified for rapid chloride penetrability test in concrete laboratories and its measuring cell sizes are according to the ASTM and AASHTO specifications. Equipped with a verification kit, Perma2™ is an accurate test device for concrete labs.

In concrete materials, the DC electrical resistance of concrete is correlated with important durability parameters of concrete such as chloride diffusion coefficient and the chloride migration coefficient that are used for the durability design or service life design of concrete structures.
Perma2™ is a laboratory device for testing the durability of concrete exposed 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
  • Stand alone operation
  • Easy-to-assemble
  • Accurate (±0.1 mA)
  • Auto-seal cells with rubber gasket and spacer (i.e. does not require caulking)
  • Flexible logging interval time (1 to 10 min)
  • Automatic temperature control system
  • Four measurement channels
  • User-friendly PC software (optional)
  • Customizable setup
  • USB connection to computer (optional)
  • Verification kit accessory (optional)

Q1: What vacuum pressure is the vacuum pump setup for conditioning the specimens?
A: According to the ASTM C1202, a vacuum pressure of 50 mm Hg should be applied. This is equivalent to a maximum of about -28 in Hg on the pressure gauge supplied with the Perma2™ vaccum pump. So, it is required to keep the pressure using the vacuum pump supplied, less than -28 in Hg during the conditioning of the RCPT specimens.

Q2: Is caulking required for the testing cell ?
A: No, caulking is not needed for Perma testing cell. The specimen should have epoxy coating, in order to keep the chloride penetration one-dimensional.
