      David, Průša; Karel, Šuhajda; Tomáš, Žajdlík; Kateřina, Svobodová; Stanislav, Šťastník; Klara, Hobzova; Venkrbec, Vaclav (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-13)
      Microwave radiation is widely utilized in construction practice, especially for drying building materials, remediating damp masonry, or sterilization of biotic pests that have infested building structures. The available scientific and technical literature reports that certain materials exposed to microwave radiation do not change their physical and mechanical properties, although this has not yet ...

    • Evaluation of optimal replacement of natural aggregates by recycled concrete aggregates to achieve sufficient durability 

      Novakova, Iveta; Sjåfjell, Jørgen J.; Venkrbec, Vaclav (Preprint; Manuskript, 2022)
      The use of recycled concrete aggregate (RCA) is one way to reduce the depletion of raw materials for the production of concrete. In this article RCA was tested and evaluated. Concrete with 25 to 80 % of RCA was examined in terms of its durability performance, particularly capillary absorption and shrinkage. Capillary absorption testing showed that RCA has better or identical results as the reference ...
