Effect of the water storage of biocomposites based on chemically treated hemp hurds on their properties

Abstract

Due to the limited amount of total world reserves of non-renewable natural resources, the increased attention is devoted to the use of alternative materials. Nowadays, the use of renewable materials such as natural fibres for reinforcement of lightweight composites is attractive. The great importance is attached to industrial hemp as rapidly renewable fibres and non-waste material. Hemp hurds is obtained from the processing of hemp stems (woody core of hemp stems) and used like a filler into composites. In this paper, the attention is given to the water storage of biocomposites based on unmodified and chemically modified hemp hurds and an alternative binder MgO-cement and to the testing of their mechanical and physical properties (compressive strength, density, thermal conductivity).
