This study mainly aimed to investigate the effects of press temperature on some properties of three-layer cement bonded particleboard made from the particles of spruce (<em>Picea orientalis</em>) and poplar (<em>Populus tremula</em>). For this purpose, a total of 16 experimental board groups with 1200 kg/m<sup>3</sup> target density and 1/3 wood-cement ratio were produced at the press temperatures of (20, 30, 40, 50, 60, 70 and 80) °C. As cement curing accelerator, CaCl<sub>2</sub> was used at a rate of 5 % (cement weight basis). The physical, mechanical and thermal properties of the boards were determined. The results indicated that the press temperature substantially affected the properties of cement-bonded particleboard depending on the wood species. In the light of this study, the optimum temperatures in producing of cement-bonded particleboard were found as 40 °C for poplar wood and 60 °C for spruce wood.</p>}, number={1}, journal={Maderas-Cienc Tecnol}, author={Yel, Husnu and Donmez Cavdar, Ayfer and Boran Torun, Sevda}, year={2020}, month={Jan.}, pages={83–92} }
