Process for enhancing the characteristics and durability of wood fiber cement and wood fiber concrete composites

摘要

The invention relates to materials, particularly composite materials and enhancement of their properties. The invention provides a method for enhancing the properties of wood fiber cement and wood fiber concrete composites comprising treating the wood fibers with an aqueous chemical before combining with cement or concrete. The aqueous chemical is preferably acrylic emulsion or alkylalkoxysilane. The treatment enhances the dimensional stability and compressive strentgh of the composites. The invention also provides the resulting composites. These enhanced composites are suitablefor use as building materials.
