HIGHLIGHTS
The test is performed applying a voltage difference between the ends of a cylindrical specimen, one end is the negative and is immersed in a sodium chloride solution, while the other end is the positive and is immersed in a sodium hydroxide solution.
Testing procedure to ASTM and AASHTO
While keeping 60 VDC difference between the specimen ends, current (Ampere) transmitted through the specimen is accurately measured over time calculating the total charge (Coulomb). This value relates to the specimen resistance to chloride ion penetration.
In accordance with the Standards indications, starting from the measured total charge, the instrument provides qualitative indications of the chloride ion penetrability level (from High to Negligible).
Two test cells are available depending on the specimen dimensions:
58-E5220/A1
Complete test cell to ASTM and AASHTO suitable for concrete specimen dia. 100 mm x 50 mm length. It includes 2 heads and cables, 1 temperature probe, 4 tie rods for cells tightening, 2 gaskets, 1 rigid plastic sleeve for hydraulic seal.
58-E5220/A2
Complete test cell to ASTM and AASHTO suitable for concrete specimen dia. 100 mm x 200 mm length. It includes 2 heads and cables, 1 temperature probe, 4 tie rods for cells tightening, 2 gaskets, 2 rigid plastic sleeves with 4 internal tie rods for hydraulic seal.
Testing procedure to NT BUILD 492
This test method requires to adjust the voltage difference starting from 30 VDC depending on the transmitted current.
The CI-METER allows continuous voltage adjustment from 5 to 70 VDC. Suggested voltages and test durations are pre-set in the instruments to drive the user to the correct test execution.
For this test method, the following kit is required:
58-E5220/A3
Migration set up kit to NT BUILD 492 for simultaneous testing of up to 3 specimens. It includes:
Transparent plastic tank
3 specimen holders with stainless steel support, plastic spacers, electrodes (+ and -), perforated grids, stainless steel clamps, rubber sleeves, cables
3 temperature probes
Test cell for chloride ion penetration meter
Two CI-METER models are available:
58-E5214
