Steel and Corrosion
Head:
Dipl.-Ing. Falk Meyer
The following investigations and services are offered:
Section Steel
- Approval testing and initial type testing:
- Reinforcing steel (bar, coil, welded mesh, lattice girder, chair)
- Prestressing steel (bar, wire, strand)
- Mechanical couplers and anchors for reinforcing steel
- External surveillance and certification of reinforcing and prestressing steel producers and further processing (reinforcing steel in coils)
- Special tests (e. g. pull-out tests for Evaluation of band properties)
- Assessment of suitability for welding
Section Corrosion
- Rapid chloride Migration test (RCM), e. g. according to guideline BAW, NT Built 492
- Chloride diffusion tests
- Carbonation testing (accelerated carbonation of test specimens)
- Measurement of electrolytic resistance (two or four electrodes)
- Potentiostatic /dynamic polarisations test, e. g. approval test for additions
- Galvanostatic /dynamic polarisation test
- Determination of polarisation resistance
- Electrochemical impedance spectroscopy (EIS)
- Determination of residual load-bearing capacity of corroded rebar
- Determination of coating thickness of ferrous metal substrates
