Abstract: Volume changes of concrete in the hardening phase and the associated cracking risk can be predicted by using calculation methods to assess the early age structural behaviour of the concrete. Based on such calculations and corresponding material parameters determined from laboratory experiments, proper choice of concrete type, mineral additives and execution methods on-site can be taken to minimize or avoid cracking. The current article constitutes a compilation of the Cost Action TU1404 RRT results from NTNU, and it aims to provide a set of parameters necessary to perform early age crack assessment of the investigated concrete. A vital part of the current test program was the Temperature-Stress Testing Machine (TSTM) at NTNU, which measures the restrained stress development of concrete through the hardening phase.
