This research was conducted to study the effect of the pressure levels (0.05, 0.07 and 0.10 kg/cm2) and cement replacement by commercial lime (0, 10, 20, 30 and 40%) on wood-cement mixture. The wood was extracted for 7 days and calcium chloride was added at 2% based on binder (s) weight. Each combination of the above treatment was replicated four times giving a total of 60 specimens blocks. The specimens were manufactured and its properties were determined. Increasing pressure from low to medium level, resulted in increasing the compressive strength and density when replacing 10, 20 and 30% lime; while the increasing from medium to high level increased the hardness and basic density
