Chloride Ion Penetration Meter

Description

This test method allows concrete to be evaluated in terms of chloride permeability, this parameter is essen­tial as it influences concrete durability.
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, the other is the positive and is 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
