The Behavior of Cement-Bonded Particleboard with Modified Composition under Static Load Stress

This article presents research on the behavior of cement-bonded particleboards under mechanical stress caused by the static load. The composition of the boards was modified using alternative raw materials–dust (DU) forming during the processing of cement-fibre boards and particle mixture (PM) genera...
