Performances des colonnes en béton confiné avec des enveloppes externes en composites « PRFC »
Un programme expérimental comprenant des essais sur 30 cylindres 160x320 mm a été mené en vue de déterminer le gain de résistance et de ductilité du béton confiné par collage externe de tissu de polymère renforcé de fibres de carbone (PRFC). Les variables étudiées sont la résistance à la compression du béton non confiné f’co, le niveau de confinement ...

Direct seeding for ecological restoration is a cost‐effective and scalable method, but its effectiveness largely relies on choosing the appropriate species. Understanding the criteria used to select species is critical for optimizing restoration outcomes, especially in the face of limited resources and ongoing environmental changes.
