A.T. (Abraham) Gebremariam



Dr. Abraham Gebremariam is an assistant professor at Resources and Recycling, Delft University of Technology. He obtained his PhD in sustainable construction materials at the Department of Energy Technology, Aalborg University (Denmark). He holds MSc in Materials Science from a joint study at the University of Aveiro (Portugal), University of Hamburg (Germany) and Aalborg University (Denmark). He has worked as a postdoc researcher at Delft University of Technology, developing a full-scale recycling technology for end-of-life concrete retrieved from construction and demolition activities. Recently, the technology has been valorised as C2CA Technologies. His current research focuses on online quality analysis of recycled aggregates using LIBS spectroscopy, circularity of construction materials, including reuse and recovering of building materials. His expertise includes thermal calcination of clays, cementitious materials, recycling technologies, hydration of cement, re-carbonation of concrete and aggregates.


Abraham’s research interests among others include,

  • Real-time characterization of recycled aggregates using LIBS spectroscopy,
  • Designing of circular concrete,
  • Activation and beneficiation of cement rich powder from EoL concrete,
  • Formulation of supplementary cementitious materials,
  • Circularity and sustainability of construction materials,
  • Recycling technologies,
  • Re-carbonation of concrete,
  • Fluid dynamics and High temperature processes.
