Concrete Resistivity Meter QualiCRM™ 4000
Concrete Resistivity Meter QualiCRM™ 4000 designed to evaluate the potential corrosion rate of reinforcing bars. The onset and progression of steel corrosion depend on the properties of the cement paste and the concrete’s permeability.
Since concrete's electrical conductivity operates through an electrolytic process—driven by ionic movement in the cement matrix’s aqueous pore solution—highly permeable concrete exhibits greater conductivity and lower electrical resistance.
Understanding a concrete’s electrical resistance offers valuable insight into the potential corrosion rate of embedded steel.
