Dr. A.T. (Abraham Teklay) Gebremariam

Dr. Abraham Teklay Gebremariam is a postdoc researcher at Delft University of Technology, Faculty of Civil Engineering and Geosciences, Resources and recycling group. He studied his PhD in Energy Technology at Aalborg University (Denmark) and his MSc in materials science at the University of Aveiro (Portugal). Currently his research focuses on recycling Construction Demolition Wastes (CDW), specifically on activating and reusing the fine fraction of end of life concrete. His expertise includes thermal calcination of clays, cementitious materials, recycled concrete aggregates, hydration of concrete and generally in recycling and reusing building materials.
