Particle Sizes and Wood/Cement Ratio Effect on the Production of Vibro-compacted Composites
ABSTRACT The aim of this study was to evaluate the influence of particle size and the wood/cement ratio on the physical and mechanical properties of vibro-compacted wood-cement composites. The effects of three different particle sizes (diameter between 1.4-2.36 mm; 2.36-4 mm; and 4-9.56 mm) and woo...
