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 has been 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.
Task Group: “Planning, execution and evaluation of corrosion surveys of steel in concrete” (download report of the Task Group meeting, published in the journal Materials and Corrosion)
