    • Biochar-Added Cementitious Materials—A Review on Mechanical, Thermal, and Environmental Properties 

      Mensah, R.A.; Shanmugam, Vigneshwaran; Narayanan, Sreenivasan; Razavi, Seyed Mohammad Javad; Ulfberg, Adrian; Blanksvärd, Thomas; Sayahi, Faez; Simonsson, Peter; Reinke, Benjamin; Försth, Michael; Sas, Gabriel; Sas, Daria; Das, Oisik (Peer reviewed; Journal article, 2021)
      The enhanced carbon footprint of the construction sector has created the need for CO2 emission control and mitigation. CO2 emissions in the construction sector are influenced by a variety of factors, including raw material ...

    • Influence of concrete’s mechanical properties on the cracking of concrete dams 

      Ulfberg, Adrian; Seger, Andreas; Bista, Dipen; Wilde, Marie Westberg; Johansson, Fredrik; Das, Oisik; Sas, Gabriel (Chapter, 2021)
      Analytical methods of structural stability assessment of concrete dams are often too simple and thus conservative in their predictions.Without the actual foundation geometry, capacity for some rigid body failure modes are ...

    • Influence of large-scale asperities on the stability of concrete dams 

      Ulfberg, Adrian; Jaime, Gonzales-Libreros; Das, Oisik; Sas, Gabriel; Andersson, Erik; Bista, Dipen; Arntsen, Bård; Seger, Andreas (Chapter, 2022)
      For concrete dams founded on rock, there are only a few options in the common analysis methods to account for large‐scale asperities. However, previous research alludes that they have a significant impact on the behaviour ...

    • Probabilistic finite element analysis of failures in concrete dams with large asperities in the rock–concrete interface 

      Ulfberg, Adrian; Gonzalez-Libreros, Jaime; Das, Oisik; Bista, Dipen; Westberg Wilde, Marie; Johansson, Fredrik; Sas, Gabriel (Peer reviewed; Journal article, 2023)
      Common analytical assessment methods for concrete dams are unlikely to predict material fracture in the dam body because of the assumption of rigid body behavior and uniform- or linear stress distribution along a predetermined ...
