    • DEVELOPMENT OF METHOD AND CRITERIA FOR EVALUATION OF DRY-WASHING EFFICIENCY WITH RE-CON ZERO EVO 

      Novakova, Iveta; Norman, Sven-Henrik; Bista, Dipen (Chapter; Bokkapittel, 2022)
      Society recognises the need for the preservation of nature and the need for better resource utilisation. Integration of good practice in the building industry is mainly targeted at reducing or completely eliminating waste. One of the waste sources in the concrete industry is created in washing facilities and consists of returned concrete, washing water and cement slurry. Concrete trucks are washed ...

    • 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 (Conference object; Konferansebidrag, 2021-09)
      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 underestimated. This is problematic when deciding upon remediation activities of a dam that is considered unstable and may divert the restoration activities from where they 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; Bokkapittel, 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 of interfaces under shear. This study investigates the behaviour of concrete dam scale models with varying interface geometries, under a realistic set of eccentric loads. The outcome ...
