Abstract: In this study, the risk of cracking at early age is assessed for different concretes, including concretes with a low heat of hydration. Characteristics of concrete at early age such as the evolution of the mechanical properties (dynamic and static Young’s modulus, dynamic shear modulus and Poisson ratio) are measured dynamically thanks to ultrasonic waves and statically by loading cycles. Autogenous shrinkage is evaluated since setting. And finally, the risk of cracking is followed using dual concentric rings for evaluating stress development due to restrained volume change.
