Abstract
This article outlines an experimental and numerical study of moisture in concrete subjected to air, water or sealed curing. For this purpose, columns of eight qualities of concrete were studied at 3 different ages each over a period of 450 days. Parallel studies of hydration, internal relative humidity, self-desiccation and strength were carried out. Finally the article presents an analysis of the internal relative humidity and the mechanisms of moisture transfer by modelling the diffusivity and the capillary conditions of 4 of the concretes. The project was carried out between the years 1989 and 1992.
Résumé
Cet article présente une étude expérimentale et numérique de l'humidité du béton soumis à l'air, à l'eau ou à une cure sous enduit de protection. À cet effet, des colonnes faites de huit qualités de béton ont été étudiées à 3 âges différentes sur une période de 450 jours. Des études parallèles ont égaleent été menées sur l'hydratation, l'humidité interne relative, l'autodessication et la résistance. Enfin, l'article présente une analyse de l'humidité relative interne et des mécanismes de transfert d'humidité par modélisation de la diffusion et de la capillarité de 4 de ces bétons. Ce projet de recherche a été mené entre 1989 et 1992.
