Rapid Chloride Ion Permeability Test Apparatus Rcpt

The PROOVEA A'it system is used to evaluate the resistance of concrete to the ingress of chloride ions in three ways:

By determining the total electrical charge that passes through a saturated concrete specimen by applying an electrical potential across the specimen in accordance with AASHTO T 277 or ASTM C1202. This is known as the AcA A Coulomb TestAcA A or the AcA A Rapid Chloride Permeability Test (RCPT).AcA A
By measuring the penetration depth of chloride ions, after an electric potential has been applied to the specimen in accordance with Nordtest Build 492 to determine the AcA A Chloride Migration Coefficient,AcA A which can be used to estimate the chloride diffusion coefficient for service life calculations.
By measuring the current passing through a saturated concrete specimen and determining the bulk conductivity in accordance with ASTM C1760.
