NDT Durability Test Apparatus

ASTM C1202 | AASHTO T277 | ASTM C1760 | NT BUILD 492 | BS 1881:204 | ASTM C666 | BS 1881:209 | NF P18-414 | UNI 9771 | ASTM C215 | AS 3583.13
Chloride Ion Penetration Meter

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:

Chloride field test set, which correlates to ASTM C114 and AASHTO T260, is used for the determination of the chloride ion concentration in concrete to enable the identification of the risk of chloride induced reinforcement bar corrosion.
It can also be used for AS 3583.13 Determination of chloride ion content.

58-E0064: Chloride field test set

The method involves an acid extraction of a representative drilled sample of concrete, which is then tested using an ion selective electrode and the potential compared with a calibration drawn up from a series of five known standard solution supplied with the test kit.

The test set includes:
  • Electronic meter battery powered with microprocessor for direct
    conversion to percentage of chloride
  • Chloride combination electrode with externally mounted temperature
    sensor, cable and connectors
