One of the possible ways of achievement of sustainable development in the building industry is moving from the limited and finite material resources to fast renewable raw material resources or materials recycled from construction wastes. Materials of plant origin belong to a large group of renewable raw materials. A great importance is attached to technical hemp like an easily renewable source of cellulosic fibers with potential for reinforcement of composite and/or only the woody core part of the hemp (shive). Renewal of scientific as well as industrial interests in the using both hemp fibres and shives in lightweight composite materials relates to a need of progress of environmental friendly products with high use value in the term of sustainable development. This article discusses the possibilities of preparing the lightweight fibrous composites based on hemp hurds slices (Hempflax) in combination with MgO-cement binder as well as some aspects of durability for hardened composites after long termed storage in deionised water by testing some important material properties as water absorbability, thermal conductivity coefficient, apparent density and compressive strength.
