The stabilized waste dust as a constituent modifying properties of wood-cement composites

Popis výsledku v původním jazyce

The research presented in this paper deals with the effect of stabilized waste dust (from cement-bonded particleboard processing) on the properties of wood-cement composites. The attention was paid to sorption characteristics and mechanical properties. The goal of the research presented was to study the properties and behaviour of wood-cement composites containing an alternative raw material once stabilised. To evaluate this aspect, composites of modified composition (filler and matrix - based on Portland and mixed cement, substitution with waste dust) were exposed to variable relative humidity ranging from 0 to 96% (increase/decrease in 10% increments). Specimens were always exposed to a given humidity (0, 10, 20, etc.) for a period of time sufficient to stabilize their weight. Absorption and then desorption took place. After the exposure to moisture was completed, the bending strength and modulus of elasticity in bending, tensile strength perpendicular to the plane of the board were tested. In this way, the effect of stabilization of spruce chips in terms of the different matrix composition of the materials was indirectly analyzed in a partial way. Sorption isotherms demonstrate the different behaviour of the materials during varying ambient air humidity. The composition of the wood-cement composites affecting the stabilization of the spruce chips (contained in the composites), among others. In case of the physical and mechanical properties a slight increase was observed.
