Rapid Chloride Permeability Test System

Product Description

The PROOVEit 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 Coulomb Test or the Rapid Chloride Permeability Test (RCPT).

• 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 Chloride Migration Coefficient, 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
