Originální abstrakt

The article presents research focused on the properties and mechanical activation of waste dust (WDC) generated during the processing of cement-bonded particle boards (CBPs). Six samples of WDC were taken directly from the CBP manufacturer CIDEM Hranice, a.s. during 2024. The properties of WDC samples were analysed with regards to its application in CBP as an active component of cement matrix. The particle size, distribution, specific surface area, density, wood content, loss on ignition, chemical and mineralogical composition, pH, microstructure, etc. were assessed. The WDC samples were then subjected to homogenization and mechanical activation in a planetary mill. The potential of mechanically activated WDC from CBP processing as a partial cement substitute was proved. While the activated WDC in an amount of 20% showed a 32% decrease in compressive strength, an 19% increase in flexural strength was also observed. As part of follow-up research, the activation process will be optimized by increasing the intensity and duration of grinding.
