Abstract

The water absorption characteristics during soaking of Terminalia superba ( Ofram), Terminalia ivorensis (Emere) as currently threatened timber species and Quassia undulata ( Hotrohotro) and Recinodendron heudelotii.(Wama) as lesser used timber species were studied to determine and compare their absorption and diffusion coefficients as potential substitutes for utilization. Water soaking was carried out for nineteen days and the data were fitted into the Fick’s model to determine both the water absorption and diffusion coefficients. The study showed that, the mean values of the water absorption coefficient at initial stages of moisture sorption for Hortrohotro, Ofram, Emere and Wama were 3.51x 10-3, 4.31x10-3, 1.67x10-3 and 8.27x10-4 (kg/m2/s) respectively. The corresponding mean values of this parameter for the entire soaking process were also determined for the timber species viz; Ofram (2.91x 10-3), Hortrohotro (2.58x 10-3), Emere (1.14x 10-3) and Wama (6.11x 10-4) kg/m2s respectively. The measured diffusion coefficient for Wama, Emere, Ofram and Hotrohotro timber species were 9.637x10,-4 6.694x10-3 4.185x10-2 and 2.899x10-2 kg/m2/s respectively. Emere and Wama had lower absorption and diffusion characteristics than Hortrohotro and Ofram. Based on this study, Wama could be substituted for Emere and Hortrohotro with Ofram.
