Scheurvorming in jong beton: Onderzoek biedt nieuwe inzichten in de spanningsrelaxatie bij jong beton
No full textBeton is tijdens het verharden onderhevig aan thermische en autogene vervormingen. Wanneer deze worden verhinderd, resulteert dit in spanningen en het risico op scheurvorming, mede afhankelijk van relaxatie. Aan de TU Delft is onderzoek gedaan naar het effect van spanningsrelaxatie op scheurvorming in jong beton. In tegenstelling tot de verwachtingen, blijkt dat spanningsrelaxatie in de eerste twee dagen juist resulteert in een verhoogd risico op scheurvorming bij bepaalde constructies met verhinderde vervorming. Ook blijkt dat autogene zwelling daarbij een significante rol speelt, die tot op heden in de norm buiten beschouwing wordt gelaten.Materials and EnvironmentConcrete Structure
