The fastest way to map corrosion in reinforced concrete
Applications:
Identifying areas of corrosion in reinforced concrete structures can be achieved through several methods of detection and monitoring. Profometer PM8500 uses half-cell potential. Using a half-cell electrode to measure the electrochemical potential difference between reinforcement steel and the concrete surface. A potential map is created, and areas with low potential readings indicate areas of active corrosion. There are other methods like It is important to note that different methods may be used in combination to obtain accurate and comprehensive results. Additionally, the expertise of a trained professional is crucial in interpreting the findings and recommending appropriate corrective actions.
Detection and monitoring of corrosion in concrete involves evaluating the corrosion potential of rebars, which are susceptible to deterioration due to exposure to aggressive environments. Estimating the corrosion potential helps in determining the current state of the rebars and identifying areas of concern. Using a portable half-cell potential meter to measure the electrochemical potential of the rebars provides an indication of the corrosion potential. By comparing the obtained values with reference values, one can assess the likelihood of corrosion occurring.

The Profometer Corrosion PM8500 is based on a technology called "Half Cell Potential". It works by measuring the electrochemical potential difference between a reference electrode and a rebar embedded in the concrete. This helps determine the likelihood of corrosion of the rebars, which can help identify areas of the structure that are at risk of corrosion and aid in making maintenance and repair decisions.

Some advantages of using Half Cell Potential to measure concrete corrosion probability are:
The reference electrode used in a half cell potential corrosion tester is selected based on the specific application and environment being tested. The PM8500 includes a copper/copper (Cu/CuSO4) reference electrode, but...
The reference electrode used in a half cell potential corrosion tester is selected based on the specific application and environment being tested. The PM8500 includes a copper/copper (Cu/CuSO4) reference electrode, but other electrodes such as the saturated calomel electrode (SCE) and the silver/silver chloride electrode (Ag/AgCl) can also be used.
Factors that can affect the accuracy of a half cell potential corrosion test include the selection of the reference electrode, the quality of the electrolyte solution, the preparation of the concrete surface being tested,...

Moisture can have a large effect of the measured potential leading to more negative values. High temperature causes concrete resistivity to be lower, which leads to more negative potentials, while low temperature causes concrete resistivity to be higher, leading to more positive potentials.
The potential becomes more positive with increasing concrete cover. Very low concrete cover can lead to more negative potentials, which may indicate higher levels of corrosion. It is recommended to measure the concrete...

We always recommend using Profometer PM8000 or GP8x00 to locate the rebar. Once the rebar is located, drill the concrete cover and connect the ground cable to it. The connection should be tested for electrical continuity, which requires at least another open point of the reinforcement to be exposed to check the resistance between the two points with an Ohmmeter (<1 Ohm).
The contact between the pore solution of the concrete and the probe can be impaired by a dried out concrete skin. This can greatly increase the electrical resistivity of the concrete.

It is recommended to moisten the surface approximately 10 to 20 minutes before carrying out the measurement.
