Corrosion Monitoring and Testing
Advanced corrosion measurement techniques.
FPrimeC Solutions offer advanced non-destructive testing methods for corrosion monitoring for bridge structures, parking garages, industrial facilities, and other structures. FPrimeC uses advanced wireless portable system for effective monitoring and measurement of corrosion probability (likelihood of corrosion), corrosion rate, and surface electrical resistivity of concrete from the surface.
Half-Cell Corrosion Potential
Half-Cell Corrosion Potential Mapping is a simple, yet very useful technique to locate and reasonably quantify areas of active rebar corrosion from the surface of concrete. The test is normally first test in the line after visual inspection. The test also provides very useful information in evaluating the state of corrosion after concrete has been repaired, and can be used to design the layout of anode in cathodic protection systems. The test practice has been standardized by ASTM, RILEM, and UNI.

Corrosion Rate Measurement
Our unique approach to corrosion rate measurement provides essential information about the kinetics of corrosion activity, with minimum intervention to the structure. The latest innovations in the field of corrosion science is used to accurately predict the corrosion rate of steel reinforcement in concrete without any connection to the reinforcement mesh. Combined with half-cell potential measurement, the method can be used to accurately detect and quantify the corrosion activity from the surface of concrete.
+ Real-time corrosion rate measurement
+ Totally non-intrusive, non-contact
+ Service-life analysis
Electrical Resistivity Measurement
Surface electrical resistivity measurements can be used to evaluate the durability properties of concrete. The test can be used as a rapid method for predicting the resistance of concrete to penetration of chloride ions. Electrical resistivity can be done as a field test, or on concrete cylinders in laboratory.
