Previous Activities



New EFC-WP11-Task Group on "Steel Corrosion in Alkali-Activated Materials" established.


  • Gregor Gluth, BAM, Berlin Germany
  • Michael Raupach, ibac, Aachen, Germany


  • passivation in alkali-activated fly ashes, slags, metakaolin and mixes
  • critical pH-values causing depassivation
  • critical chloride content
  • corrosion mechanisms and test methods for the estimation of corrosion rates

The first meeting was held at BAM in Berlin with 17 participants from 9 countries.

It is planned to have two meetings per year and prepare a state of the art report of the topics mentioned above after about 3 years as papers in Materials and Corrosion or a green book.
