Numerous studies have been carried out to characterize the autogenous shrinkage of cement-based materials in free conditions at early and very early age. But the results obtained are not sufficient to understand the autogenous volume variations of concrete in realistic structural conditions. Indeed, the analysis of such deformations requires investigating the cementitious system’s behaviour in restrained conditions, when the internal stresses generated can lead to the premature cracking of the material.
