Corrosion of Rebars in Concrete
Reinforced concrete will invariably be subjected to a corrosion process that ultimately leads to a total failure of the
structure. Accurate field potential measurements aid in detecting corrosion in rebars. Corrosion of steel in concrete is an
electrochemical process. A potential field can be measured on the concrete surface by the use of an electrode, known as a half-cell and a high-impedance voltmeter. The Canin+ Corrosion Analyzing Instrument highlights corrosion activity before rust becomes visible. Early detection is a key factor in preventing an unanticipated structural failure.
Corrosion Analysis allows the contractor to limit the maintenance tasks on reinforced concrete to the areas where it is really required. The Canin+ is the fastest instrument for corrosion analysis, offering a practical, cost-effective approach to the investigation of reinforced concrete. Corrosion analysis with the Canin+ allows a rapid, comprehensive test of the site and provides a fast assessment of locations where corrosion is likely to take place.
Corrosion analysis with the half-cell potential method: accurate field potential measurements aid in detecting active corrosion in rebars.
- Immediate presentation of test area and reading directly on the instrument’s display
- Total memory for 235’000 readings which can be stored
- For further analysis, the Software allows downloading, presenting and editing data measured by this instrument for corrosion analysis
The Windows based software makes it possible to download, present and edit data measured by the Canin+ Corrosion Analyzing Instrument in a fast and easy way using any PC. The program generates a potential map, a relative frequency and a cumulative frequency diagram and provides a chipping graph. This statistical presentation is the basis for an efficient interpretation of the half-cell potentials by the corrosion engineer.
The software allows the engineer to rotate and mirror files.
Single potential maps can be combined to form a complete graph representing the total investigated surface area. These features support the fast generation of measurement reports. Data can be easily exported to third party software for further processing.
