The relationships between the physical and mechanical properties of wood cement particleboard made from poplar and the technological parameters: density, wood/cement ratio, water/cement ratio, additive and additive′s amount were studied. The results showed that among the density, wood/cement ratio, water/cement ratio, density had the largest influences on board′s properties; wood/cement ratio was the second, and the water/cement ratio had the least. The board′s properties such as MOR, MOE, IB could be described by density (D.), wood/cement ratio (W/C), water/cement ratio (W,1,/C)with the following equation, Y=a,0,+a,1,D+a,2,(W/C)+a,3,(W/C),2,+a,4,(W,1,/C)+a,5,(W,1,/C),2,. Among the three additives, the results of adding. CaCl,2,was the best.
