Étude comparative de modèles phénoménologiques décrivant le comportement au jeune âge du béton. Partie 1.

Abstract

A comparative study of phenomenological models used to describe the behavior of concrete at early age was realized. The main objective of this review is to evaluate the ability of various models to predict the autogeneous shrinkage and the basic creep of concrete. The report also proposes some improvements to these models. This constitutes the first part of a series of two complementary papers.Key words: concrete, early age, phenomenological models, thermal deformation, autogeneous shrinkage, restrained shrinkage, basic creep, basic relaxation, induced stress, maturity.
