This study is part of general problem of developing innovative buiding materials with low environmental impact. For this purpose, tests were carried out for the formulation of cementitious composites based on rhun fibers (borassus aethiopum mart.) and rice huks. The results allowed to obtain the optimal proportion in biomass particles and water content which lead to the best physical and mechanical properties of the composites. Thus, in the case of cement and rice husks mixtures, mechanical strengths decrease with an increase of particle size. On the other hand, in the case of rhun fibers composite, mechanical resistance increase with fibers size. The results also show that physical and mechanical properties of rhunr fibers composites are better than those based on rice husks.
Author Keywords: rhun fibers, rice husks, cement, biomass, physical properties, mechanical properties.

Thus, in the case of cement and rice husks mixtures, mechanical strengths decrease with an increase of particle size. On the other hand, in the case of rhun fibers composite, mechanical resistance increase with fibers size.

Abstract: (french)
Ce travail s’intègre dans la problématique générale de développement de matériaux de construction innovants à faible impact environnemental. A cet effet, des essais de formulation de composites cimentaires à base de fibres de ronier (borassus aethiopum mart.) et de balles de riz ont été réalisées. Les résultats permettent d’identifier les proportions optimales en particules et en eau qui conduisent aux meilleures propriétés physiques et mécaniques des composites. Ainsi, dans le cas des mélanges ciment et balles de riz, les résistances mécaniques baissent avec l’augmentation de la taille des particules. Par contre dans le cas des composites à base de fibres de ronier, les résistances augmentent avec la taille des fibres. Les résultats montrent également que les performances physiques et mécaniques des composites à base de fibres de ronier sont meilleures que celles à base de balles de riz.
Author Keywords: fibres de ronier, balles de riz, ciment, composites cimentaires, biomasse, propriétés physiques, propriétés mécaniques.
