Influencia de los Tratamientos de Mineralización de la Madera en las Propiedades Mecánicas de los Compuestos de Madera-Cemento

Abstract

Wood-cement composites are non-traditional materials for structural and isolation purposes. The main inconvenient affecting its manufacture is the incompatibility between wood and cement, caused by setting inhibitory substances naturally present in woods. The knowledge of wood-cement composites is rather limited for local raw materials. This work evaluates the influence of three wood treatments -aqueous extraction, alkaline hydrolysis and polymer coating- on mechanical properties of wood fibers and of final wood-cement composites. Tensile properties of individual wood fibers and compression properties of wood-cement composites were studied for evaluation of mechanical behavior. The alkaline hydrolysis was found as the most effective treatment for suppression of inhibitory effects, followed by polymer coating and aqueous extraction methods
