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)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. This paper presents the ... -
The effect of curing temperature on autogenous deformation of fly ash concretes
Klausen, Anja Birgitta Estensen; Kanstad, Terje; Bjøntegaard, Øyvind; Sellevold, Erik Johan (Peer reviewed; Journal article, 2020)For concrete subjected to restrained conditions, autogenous deformation (AD) and thermal dilation (TD) are the main driving forces behind stress development in the hardening phase. Generally, AD in concrete is modelled by ... -
Rheology of Particle Suspensions: Fresh Concrete, Mortar and Cement Paste with Various Types of Lignosulfonates
Wallevik, Jon Elvar (Dr. ingeniøravhandling, 0809-103X; 2003:18, Doctoral thesis, 2003)The major issue concerns how the different lignosulfonate types changes the rheological properties of the cement based material (concrete, mortar and cement paste) as a function of temperature and time. In such terms, it ... -
The effect of realistic curing temperature on the strength and E-modulus of concrete
Klausen, Anja Birgitta Estensen; Kanstad, Terje; Bjøntegaard, Øyvind; Sellevold, Erik Johan (Journal article; Peer reviewed, 2018)The strength and E-modulus of concrete are decisive parameters when it comes to ultimate limit state design, serviceability limit state design, and early age crack assessment. The properties of concrete are generally ...
