Rapid Chloride Permeability Tester
Proove’ it Rapid Chloride Permeability Tester is a reliable device used to determine chloride permeability characteristics of concrete. The simple Rapid Chloride Permeability Test (RCPT) is performed on concrete specimens taken from cores or test cylinders.
The electrical current flow is measured across a 4x2in (102x51mm) dia.xH specimen positioned in a test cell with fluid reservoirs at each end. The negative end is immersed in a 3% sodium chloride solution and the positive end is in a 0.3N sodium hydroxide solution. The specimen is subjected to a 60V DC potential across the ends for six hours. The more permeable the concrete, the higher the total charge or Coulombs passed across the specimen will be.
The tester includes a microprocessor power supply module that distributes precisely controlled voltage to as many as eight RCPT specimens simultaneously. Windows®-based software installed on the user’s PC controls test parameters, stores test data and prepares professional quality reports that can be customized with a company logo. Electrical current readings are updated every five seconds, and a predicted six-hour Coulomb value is generated every five minutes. Test results can be exported to Excel for comprehensive statistical analyses of the results. Software, power cord, serial cable, and manual are included. Testing time and parameters are programmable as required.
The Proove’ it system can also be adapted for ASTM C1760 Bulk Electrical Conductivity Testing (inquire for more information), and to determine Chloride Migration Coefficient as described in NordTest Build 492. Voltage settings can be adjusted from 5 to 60V in 5V increments.
Specimen Cells are required for use and purchased separately. The Cells include sealing rings for 4in (102mm) diameter specimens, connecting cables, and a temperature probe. Each cell consists of two plexiglass end-caps with embedded conductive mesh and required electrical connections. Sealing Rings adapt Specimen Cells for use with 100mm (3.9in) specimens. Inquire for a special cell with cooling fins for testing highly permeable concrete or for tests requiring constant temperatures.
For efficient sample conditioning, the Vacuum Chamber saturates 4 to 6 samples at a time. The user can operate with their own vacuum pump, or the larger Vacuum Chamber has a capacity for up to 20 specimens. A user-supplied vacuum pump or the Vacuum Pump is available for use with it. The Verification Unit verifies output from the Proove’ it Controller.
