Half Cell Potentiometer Test

The instrument measures the potential and the electrical resistance between the reinforcement and the surface to evaluate the corrosion activity as well as the actual condition of the cover layer during testing.

Half cell potentiometer test.

The greater the potential the higher the risk that corrosion is taking place. The instrument measures the potential and the electrical resistance between the reinforcement and the surface to evaluate the corrosion activity as well as the actual condition of the cover layer during testing. Half cell potentiometer test. It is used to determine the probability of corrosion within the rebar in reinforced concrete structures.

Standard test method for corrosion potentials of uncoated reinforcing steel in concrete. The name half cell surveying derives from the fact that the one half of the battery cell is considered to be the steel reinforcing bar and the surrounding concrete. Ahc 100 at rs 30000 set in new delhi delhi. The electrical activity of the steel reinforcement.

Demonstration of astm c876 standard test method for half cell potentials of uncoated reinforcing steel in concrete. Corrosion of reinforcing steel is an electro chemical process and the behaviour of the steel can be characterised by measuring its half cell potential. Half cell potentiometer test. An electrical contact is established with the exposed steel the half cell is moved across the surface of concrete for measuring the potentials.

This blog dives into the specifics of concrete. Avantech engineering consortium private limited offering avantech semi automatic half cell potentiometer test model name number. Get contact details and address id. Half cell potentiometer test principle procedure.

An electrode forms one half of the cell and the reinforcing steel in the concrete the other. Then generally readings taken are at grid of 1 x 1 m for slabs walls and at 0 5 m c c for column beams. The half cell potentiometer is used to measure the half cell potential of reinforcement steel in concrete in accordance with astm c876 for assessment of corrosion in steel reinforcement. The half cell potential test is the only corrosion monitoring technique standardized in astm c876 15.
