The production variables investigated were three wood particle types (flakes, flake-sawdust mix and sawdust), three chemical accelerators (CaCl2, MgCl2 and AlCl3) and four wood-cement ratios (1:2.0, 1:2.5, 1:3.0 and 1:3.5). The accelerators were based on 2% by weight of cement used. The boards produced were subjected to physical tests such as density, percentage water absorption and thickness swelling. Mechanical properties evaluated were modulus of rupture, internal bonding strength and compressive strength. The results revealed that the type of particle used, wood-cement ratio and chemical additives had a marked influence on the physical and mechanical properties of the boards (p < 0.05). From quality view point, flake-sawdust composite ranked best while flake boards ranked least. Similarly, CaCl2 had the best influence on the set...
