The physical and mechanical properties of composite boards produced from cement and wood particles in the forms of sawdust and flakes from Gmelina arborea wood were determined. Two types of boards were produced: single-layered boards with only sawdust and three-layered boards with sawdust on the surface layer and flakes in the core. Both types of boards were made with four different cement–wood ratios: 1:1, 2:1, 2.5:1 and 3:1. The boards were tested for physical and mechanical properties such as actual density, water absorption, thickness swelling, modulus of rupture and modulus of elasticity. The actual density of single-layered boards ranged from 664.08 to 1200 kg m-3, while the three-layered boards ranged from 490.38 to 1097.98 kg m-3. The water absorption and thickness swelling of single-layered and three-layered boards varied from 0.55 to 6.86 % and 0.63 to 4.51 %, respectively. The average values of Modulus of Elasticity for single-layered and three-layered boards were 638.17 to 5772.11 (N/mm2) and 417.16 to 2281.34 (N/mm2), respectively. The average values of the Modulus of Rupture for single-layered and three-layered boards were 1.69 to 7.40 (N/mm2) and 1.18 to 4.28 (N/mm2), respectively. Single-layered wood cement composite boards produced with sawdust alone had higher mechanical properties than three-layer boards made with sawdust as the face layers and flakes as the core.
