• Bruk av AVA-måler for å studere porestruktur i fersk betong 

      Knutsson, Jon Emil Tobias (Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-14)
      Alle konstruksjoner som blir bygd ute i Norge vil kunne bli utsatt for frost. Frostbestandighet er en faktor som må tas høyde for under støping av betong ute. I NS-EN206 står det at kravet for frostbestandig betong er ...
    • Crack formation and Crack propagation into the compression zone on reinforced concrete beam structures 

      Kakay, Samdar; Bårdsen, Daniel; Gudmestad, Ove Tobias (Journal article; Peer reviewed, 2017)
      Crack formations in concrete may cause major damages in concrete structures. These damages require extensive maintenance work and thus have high costs. This paper addresses issues such as what causes cracks in concrete ...
