Precise and robust predictions of autogenous shrinkage of high performance concrete are essential to limit self-induced stresses and cracking in modern concrete structures. This paper presents predictions of autogenous shrinkage for three cement pastes of ...

Autogenous shrinkage is the unrestrained volume change of cementitious materials occurring at con-stant temperature without any change in mass. It occurs as a consequence of self-desiccation (de-crease of internal relative humidity) and increasing capillar ...

High-performance concrete is sensitive to early-age cracking, mainly due to its rapidly-developing autogenous shrinkage. Autogenous shrinkage and internal relative humidity (RH) decrease are direct consequences of the emptying of capillary pores due to cem ...
