Abstract
In this article, an extensive experimental and numerical study of self-desiccation and its importance in concrete technology is outlined. For this purpose, cubes and cylinders of eight qualities of concrete were studied at 4 different ages for each one. Parallel studies of autogeneous shrinkage, basic creep, hydration, internal relative humidity and strength were carried out. Previous research in the field is summed up. Finally, the article presents the mechanisms of self-desiccation as well as its importance in concrete technology by modelling the autogenous shrinkage and its effect on basic creep. This project was carried out between the years 1992 and 1995.
Résumé
Cet article présente une vaste étude expérimentale et numérique sur l'autodessication; son importance dans la technologie du béton est passée brièvement en revue. Des cubes et des cylindres de huit qualités différentes de béton ont été étudiés, chacun à quatre âges différents. Des études parallèles ont été menées sur le retrait endogène, le fluage, l'hydration, l'humidité interne relative et la résistance. Des recherches antérieures dans ce domaine sont résumées. Enfin, l'article présente les mécanismes de l'autodessication et son importance dans la technologie du béton par la modélisation du retrait endogène et de son effet sur le fluage. Ce projet de recherche a été mené entre 1992 et 1995.
