PROOVE’it Germann Instruments’ rapid chloride permeability test (RCT) system is used to accurately and quickly determine the chloride ion content from acid/water soluble powder samples of concrete obtained on site or in the laboratory.

The test involves obtaining the powdered sample from the structure or fresh concrete and mixing into a distinct amount of extraction liquids to extract chloride ions and remove disturbing ions such as sulfides. A calibrated electrode is submerged into the solution to determine the amount of chloride ions, which is expressed as a percentage of concrete mass.
