Application of technical hemp into the structure of cement-chip boards

Popis výsledku v původním jazyce

Cement-chip boards are building elements that combine the advantageous properties of wood and cement. It is this synergistic effect which determines the versatile use in the building industry. The boards can be used in any place where the favourable properties of this construction material can fully be appreciated. The disadvantage of the cement-chip boards remains in their relatively high price. Reduction of the price and possible improvement of physical and mechanical properties can be achieved by partial substitution of the raw materials. The basic ingredients of the cement-chip board include the binding material (cement) and filler (wood). The filling material may be partially replaced by secondary raw materials or completely replaced by other herbal sources, such as technical hemp. As the individual components mutually influence each other and, as their effects may not only be added up (additive effect), but also mutually reinforced (synergistic effect), it is not so easy to determine the optimal recipe as it may seem at first sight. This article deals with the use of technical hemp shives as a replacement of filling component of the cement-chip boards. To evaluate the possibility of future use of the boards in building structures, the physical and mechanical properties were monitored. Special emphasis was placed on tests of flexural strength, modulus of elasticity and volume weight. The mixture must meet the technical parameters related to the cement-chip boards.
