Abstract
An overview is given of a global research program performed at Ghent University, concerning early age concrete. More specifically the carly age thermal cracking due to the heat of hydration in hardening massive concrete elements has been focused. A fundamental approach was followed, based on the degree of hydration. By means of the degree of hydration, a fundamental and very accurate description of early age concrete behaviour can be realised. The resulting material laws can be applied within a further study of the durability of massive concrete structures in marine environment. In this way, the fundamental study of early age concrete behaviour can serve as a basis for further durability improvement of concrete structures.
Résumé
Cet article donne l'aperçu d'un programme global de recherche concement le comportement du béton pendant sa phase de durcissement. Plus spécifiquement, on se concentre sur le problème de la fissuration thermique dans le béton jeune, provoquée par la chaleur d'hydratation. Une approche fondamentale est présentée, basée sur le degré d'hydratation. En utilisant ce paramètre, une description fondamentale et précise du comportement du béton jeune peut être réalisée. Les lois de matériau qui en résultent, peuvent être appliquées dans une étude concernant la durabilité des constructions massives en béton situées dans des conditions maritimes. De cette manière, l'étude fondamentale du comportement du béton jeune peut être appliquée afin d'améliorer la durabilité des constructions en béton.
