Calibration of material models against TSTM test for crack risk assessment of early-age concrete containing fly ash
Ji, Guomin; Kanstad, Terje; Bjøntegaard, Øyvind (Journal article; Peer reviewed, 2018-05-09)Making reliable cracking risk assessment involves experimental testing and advanced modeling of the time- and temperature-dependent behavior of the properties, the restraint conditions of the structure, and the external ... -
Crack risk evaluation of submerged concrete tunnel during hardening phase
Ji, Guomin; Kanstad, Terje; Bjøntegaard, Øyvind (Journal article; Peer reviewed, 2018-12-23)Cracking of concrete structures during the hardening phase often seriously compromises not only structure integrity but also durability and long-term service life. Especially for large massive structures, for example, ... -
Early age crack assessment of concrete structures: Experimental and theoretical approaches
Klausen, Anja Birgitta Estensen; Kanstad, Terje; Bjøntegaard, Øyvind (Chapter, 2017)The present paper contains a brief overview of work performed within the Ph.D.thesis "Crack assessment of concrete structures: experimental investigation of decisive parameters" (2010 – 2016). The main objective of the ... -
Excavated rock materials from tunnels for sprayed concrete
Luong, Judy Yuen Wah; Aarstad, Kari; De Weerdt, Klaartje; Bjøntegaard, Øyvind (Chapter, 2017)Sand extracted from natural resources is widely used in concrete production nowadays. The increase in demand for concrete production has resulted in shortage of natural sand resources, especially in terms of suitable ... -

Sandbakk, Sindre; Kanstad, Terje; Bjøntegaard, Øyvind; Vandewalle, Lucie; Parmentier, Benoit (COIN Project report;23, Research report, 2010) -
Local use of rock materials – production and utilization State-of-the-art
Petersen, Berit Gudding; Martinez, Cristina Ramos; Gunther, Daniel; Macias, Javier; Mathisen, Lillian Uthus; Fladvad, Marit; Haugen, Marit Kristin; Nålsund, Roar; Danielsen, Svein Willy; Bjøntegaard, Øyvind (Research report, 2019)During excavation of tunnels, large amounts of rock material are produced. This excavated rock material is utilized to a varying extent for road-, railway- and concrete purposes, but significant amounts are used as deposits ... -
Numerical modelling of field test for crack risk assessment of early age concrete containing fly ash
Ji, Guomin; Kanstad, Terje; Bjøntegaard, Øyvind (Journal article; Peer reviewed, 2018-09-09)The high-strength/high-performance concretes are prone to cracking at early age due to low water/binder ratio. The replacement of cement with mineral additives such as fly ash and blast-furnace slag reduces the hydration ... -
Property development and cracking tendency in hardening concrete: Effect of cement type and fly ash content.FA 3 Technical performance. SP 3.1 Crackfree concrete structures
Bjøntegaard, Øyvind; Kjellesen, Knut O. (COIN Project report;40, Research report, 2012)The concrete mix design influence the risk of thermal cracking in the hardening phase. Here the effect of binder composition has been investigated, where the variables are cement type and fly ash dosage. The fly ash was ... -
