INTERNATIONAL WORKSHOP ON ALKALI - ACTIVATED MATERIALS
On Thursday, May 11th, 2017, ZAG hosted the INTERNATIONAL WORKSHOP ON ALKALI - ACTIVATED MATERIALS (“geopolymers”) and a meeting of the technical committee RILEM TC 247 DTA (Chair: Prof. John L. Provis; Secretary: Dr Frank Winnefeld). The Technical Committee 247– DTA (Durability testing of alkali– activated materials) deals with the durability aspects of alkali activated materials (AAM), in particular the determination of resistance to frost, carbonation, penetration of chlorides and other aggressive media.
Programme:
- Welcome by director of ZAG (A. Legat)
- Presentation of ZAG’s activities related to AAMs (V. Ducman)
