i-cov is suitable for on-site conditions assessment of steel reinforced concrete structures. The methods can be applied regardless of the thickness of concrete cover and the reinforcement size of detailing.

i-rom

Resistance of Material

Concrete or mortarsâ€™ resistivity in its basic definition is a material property, which is influenced by the environment. Resistivity measurements are the inverse of conductivity and represent the materials ability to resist current flows.

i-cos

Corrosion of Steel

i-cos applies a small (20 mV) potential difference between the steel and a secondary electrode on the surface, which results in a small current flow. This is then proportional to the inverse of polarization resistance and hence is directly proportional to the corrosion rate.

i-vos

Voltage of Steel

i-vos is the measurement of the voltage of embedded steel withing concrete or masonry (electrolyte). i-vos measurements provide an indication of corrosion activity and a probability of risk in accordance with ASTM standards.

i-tom

Thickness of Metal

i-tom metal thickness measurements are critical in understanding the amount of section loss of a structural member. The values are reflective of the corrosivity index of the environment as well as the stability of the structure.
