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)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)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, ... -
Cracking risk of concrete structures in the hardening phase: Experiments, material modeling and finite element analysis
Ji, Guomin (Doktoravhandlinger ved NTNU, 1503-8181; 2008:198, Doctoral thesis, 2008) -
Evaluating the effective thermal conductivity of cement mortar through x-ray scanning
Asadi, Iman; Ji, Guomin; Haj Mohammadian Baghban, Mohammad (Peer reviewed; Journal article, 2022)The effective thermal conductivity of cement mortar as a porous material depends on its solid phase and void phase conductivity. Therefore, a sample's pore distribution can highly impact the value of effective thermal ... -
Hollow core slabs in the assembly process - Structural behaviour and strength during positioning of elements
Kanstad, Terje; Cantero, Daniel; Kristoffersen, Martin; Ji, Guomin (Research report, 2023) -
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)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 ...
