About the Book

Les coques de palmiers à huile (OPS) sont des ressources renouvelables obtenues à partir de produits agricoles solides après l'extraction de l'huile de palme. Une étude sur la préparation du béton léger (LWC) en utilisant des agrégats d'OPS avec et sans traitement thermique a été réalisée. Des fibres torsadées de polypropylène à haute performance (PPTBF) ont été incorporées dans cet OPSC à différentes fractions de volume (Vf) (0, 0,25, 0,5, 0,75 et 1 %). Les performances des mélanges OPSC avec et sans béton renforcé de fibres OPS traitées thermiquement (OPSFRC) ont été évaluées en effectuant une série d'essais complets. Les propriétés fraîches et mécaniques de ces mélanges de béton, telles que l'affaissement, le Vebe, la densité, la résistance à la compression, la résistance à la traction, le module d'élasticité (E) et le comportement contrainte-déformation, ont été décrites. Des essais de pénétration rapide du chlorure (RCPT), de mesure de la porosité, d'absorption d'eau et de retrait de séchage ont été réalisés afin d'évaluer les effets de l'OPSFRC traité thermiquement sur la durabilité. L'utilisation du PPTBF a permis de réduire la perméabilité, la porosité capillaire et l'absorption d'eau grâce à l'effet de blocage des pores. Il a également été conclu que la quantité optimale de PPTBF est de 0,5% Vf.
