Alkali Aggregate Reactions (AAR) in concrete. The Norwegian endeavour during more than 3 decades of research
Wigum, Børge Johannes; Lindgård, Jan; De Weerdt, Klaartje; Pedersen, Bård Magne; Rønning, Terje F. (Chapter, 2022)It is now more than 80 years since Alkali Aggregate Reactions (AAR) first were reported as a deleterious deterioration mechanism in concrete. In Norway, AAR was recognised in the late nineteeneighties. Norwegian experience ... -
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

Freeze-Thaw Resistance of Concrete: Effect of: Curing Conditions, Moisture Exchange and Materials
Rønning, Terje F. (Dr. ingeniøravhandling, 0809-103X; 2001:4, Doctoral thesis, 2001)Research on freeze-thaw resistance of concrete in general and on curing and moisture conditions in particular is motivated from an economic and product sustainability point of view. Specifically, it is argued for the ... -
Fundamental study on ASR kinetics - effect of temperature on aggregate reactivity and pore-water composition
De Weerdt, Klaartje; Hemstad, Petter; Justnes, Harald; Østnor, Tone Anita; Rønning, Terje F.; Lindgård, Jan (The International Conference on Alkali-Aggregate Reaction (ICAAR);Theme 4, Chapter, 2021)
