Abstract: Many durability issues faced by concrete structures find their origin in initially present micro-cracks. Early-age cracking due to restrained deformations occurs at a time when concrete properties evolve, while the rate of deformations is still very high. This study confronts the predictions provided by CEB-FIP Model Code to actual measurements of the stress development in fully restrained deformations conditions with a TSTM device. It is observed that such modelling strategies can hardly be applied, especially in presence of supplementary cementitious materials (SCM). Recommendations are made for a more accurate modelling of the early age stress development in restrained deformation conditions.
