Preface: Slabs cast on ground or additionally supported by piles are subjected to restraint. The motor of restraint are the three free thermal deformations in conjunction with autogenous shrinkage. Such restraint my lead to cracks at early age. Practice deals with restraint in widely differing ways, especially with respect of the assumptions regarding the type and magnitude of restraint. Usually, the present methods and computational softwares do no accurately take the young concrete´s rapid hardening into account. It is the aim of this report to present the usual models for the assessment of restraint, to validate and modify them. Improved models with adequate accuracy to assess the restraint in the phase of predesign, desin and execution.
