Abstract
It is important from the economics point of view to understand the behaviour of concrete under loading due to plain water jets. Investigations which are based on mass removal measurements, grain size analysis, and mercury intrusion show that the performance of failure can be described using fracture mechanics methods. The reactions of hardened cement paste and concrete differ widely from each other because of the influence of interfaces between the cement paste and the aggregate.
Resume
D'un point de vue économique, il est important de comprendre le comportement du béton soumis à des jets d'eau haute pression. Des recherches qui s'appuient sur des mesures de perte de masse, d'analyse granulométrique et de pénétration de mercure montrent que l'on peut décrire le comportement mécanique en utilisant les méthodes de la mécanique de la rupture. Les réactions de la pâte de ciment et du béton différent beaucoup l'une de l'autre. Ceci est dû à l'influence des interfaces entre la pâte de ciment et le granulat.
