Résumé :

The use of lignocellulosic residues in the composite materials manufacture, based on hydraulic binder, as fiber, has shown to improve the mechanical behaviour of the material, preserve the environment and develop a growing need for degradable plant products exploitation. Moreover, this may certainly offer alternative traditional materials. The aim of the present work is to characterize a cement palm date fibre composite to be used in the manufacture of new structural materials and isolation. The study focuses on the fiber dimensional stability which is sensitive to water. The presence of organic matter has been proved to be detrimental to the durability of untreated fiber-reinforced composite. The fibers were treated with boiling water to extract organic matter and then coated with several kind of product. The heat treatment associated with the cement coating in particular, has led to considerable improvement in the fiber water sensitivity and the mechanical behaviour of composite ductility. © 2009 Praise Worthy Prize S.r.l. - All rights reserved.
