Alkali-silica reaction (ASR)-performance testing: Influence of specimen pre-treatment, exposure conditions and prism size on alkali leaching and prism expansion
Lindgård, Jan; Thomas, Michael D.A.; Sellevold, Erik Johan; Pedersen, Bård; Andiç-Çakır, Özge; Justnes, Harald; Rønning, Terje F. (Journal article; Peer reviewed, 2013)Whether or not concrete prism tests developed for assessment of alkali-silica reactivity of aggregates might be suitable for general ASR performance testing of concrete has been evaluated. This paper discusses how variations ... -
Alkali–silica reaction (ASR)—performance testing: Influence of specimen pre-treatment, exposure conditions and prism size on concrete porosity, moisture state and transport properties
Lindgård, Jan; Sellevold, Erik Johan; Thomas, Michael D.A.; Pedersen, Bård; Justnes, Harald; Rønning, Terje F. (Journal article; Peer reviewed, 2013)Abstract Whether or not concrete prism tests (CPTs) developed for assessment of alkali-silica reactivity of aggregates might be suitable for general ASR performance testing of concrete has been evaluated.

Filler and Water Reducer Effects on Sedimentation, Bleeding and Zeta-Potential of Cement Paste
Peng, Ya; Pedersen, Bård; Ng, Serina; De Weerdt, Klaartje; Jacobsen, Stefan (Journal article; Peer reviewed, 2018)Bleeding and sedimentation quantify the stability of fresh cement paste, whereas the addition of fillers and water reducers affect the stability. The effect of various types of fillers and water reducers was investigated ... -

Prevention of ASR by use of low alkali OPC and silica fume. Field and lab studies from the Maridal culvert and the Storo bridge in Oslo, incl. assessment of residual expansion
Pedersen, Bård; Rodum, Eva; Haugen, Marit Kristin; Lindgård, Jan (Peer reviewed; Journal article, 2021)In 1999, the Maridal concrete culvert was built in Oslo, Norway. Natural aggregates known to be moderately alkali reactive according to laboratory and field experience were used. Field survey combined with microstructural ... -
