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

The Technical Group Steel is accredited according to DIN EN ISO/IEC 17025:2005. You find the accreditation certificate here.

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
