Cement-bonded particleboards merge the good properties of wood and cement; they are board materials with properties which are pre-determined for use in many different cases in the case of construction of walls and partition walls, lower ceilings, facades, floors, etc. The disadvantage of the cement-bonded particleboards is the relatively high price which is mainly derived from the price of input materials. The main component creating the filler for cement-bonded particleboards is wood. Wooden chips are produced from tree trunks of cut trees which mean that, first of all, it is necessary to produce chips from the wooden substance. By using alternative fillers, it is possible to partially or wholly avoid this part of the production. The use of alternative raw materials in construction materials means there is the opportunity to decrease manufacturing costs and eliminate ecological loads. The content of this paper is the use of alternative fillers as an organic, as well as inorganic origin in the structure of cement-bonded particleboards. For the production of boards, technical hemp was selected, straw and jute as representatives of the most often used organic raw materials followed by a narrow fraction of Refaglas cellular glass, synthetic fibres and waste from the production of ORSIL mineral wool. In the board structure, this concerned 100% or 50% substitution of wooden splinter. For the valorisation of options for future use in board materials, physical-mechanical properties were monitored; in particular, attention was paid to bending strength, modulus of elasticity in bending and bulk density. Newly created boards must fulfil the technical parameters required for cement bonded particleboards stated by the standard EN 634-2.
