7th International Workshop:
Mechanisms and Modelling of Waste/Cement Interactions

Scope and Background

The workshop “Mechanisms and Modelling of Waste/Cement Interactions” focuses on the understanding and modelling of the processes responsible for the stabilisation of hazardous and radioactive wastes in cementitious systems, and on the use of mineral wastes as cementitious (raw) materials. Like the very successful earlier meetings in this series of workshops (Meiringen, 2005; Le Croisic, 2008; Ghent, 2013; Murten, 2016; Karlsruhe, 2019; Prague, 2023), the 7th workshop on Mechanisms and Modelling of Waste/Cement Interactions intends to bring together world-leading and junior scientists from the different branches of the research community.


The workshop aims at exchanging state-of-the-art knowledge on mineralogical, chemical and physical processes of waste/cement interactions.
  • Cement Chemistry and Microstructure
    Modelling, multiscale-approaches, alternative cements
  • Cement/Rock/Soil Interfaces and Transport
    Cement/host rock, transport processes, and modelling
  • Recycling of Mineral Wastes in Cement Production
    Raw material replacement, supplementary cementitious materials, substitution potential, and eco-efficiency
  • Interaction of Cement with Waste Constituents
    Radwaste, toxic waste, metal binding mechanisms, organic compounds
  • Nanoscale Characterisation and Molecular Dynamics
    Methods at large scale facilities, advanced methods
  • Deterioration and Leaching
    Alkali-aggregate reaction, carbonation, sulfate interaction, ageing processes, natural analogues

Workshop location

In the centre of Bern, just a few steps from Bern main train station, with a spectacular view to the Alps and the medieval town (UNESCO Cultural World Heritage Site). Bern is well connected to the European train system, has a small airport, and is easily reached by train from Zurich, Geneva and Basel airports.
