Classification: CPC G  B | IPC B  G

Claim 0:
1. A method of performing an assessment of a predetermined characteristic of a concrete structure comprising:
applying a narrow electrical pulse to a pair of first electrodes in contact with an area of the concrete structure containing a rebar;
measuring a time dependent voltage response from a pair of second electrodes in line with and between the pair of first electrodes and in contact with the area of concrete structure containing the rebar;
fitting the measured time dependent voltage response to a theoretical transient to establish a fitted transient function;
determining constants of the fitted transient function; and
determining one or more electrical equivalent circuit elements of an equivalent circuit model of the concrete structure containing the rebar in dependence upon the constants of the fitted transient function; and
the predetermined characteristic of the concrete structure is established in dependence upon the determined one or more electrical equivalent circuit elements of the equivalent circuit model of the concrete structure.
