Physical properties of two tropical wood species from Mozambique
Abstract:Abstract

The aim of this study was to reveal some important physical properties of two lesser used wood species from Mozambique. Density of wood, green moisture content (MC), shrinkage, swelling, sorption–desorption behaviour and quantitative colour analyses were carried out to facilitate the potential use of Icuria dunensis (ncurri) and Pseudolachnostylis maprounaefolia (ntholo). The study found that the average densities at 12% MC were 907.1 kg m?3 for ncurri and 1023.4 kg m?3 for ntholo. The average values of green MC were 31.4% for ncurri and 39.2% for ntholo. Ncurri and ntholo wood showed low coefficients of anisotropy for heartwood, 1.3 and 1.4, respectively. The colour measurements described the patterns of radial and longitudinal variations in wood colour. In conclusion, ntholo and ncurri are characterized by high density and dimensional stability. Ntholo can be used where small dimensional changes are required, e.g. in joinery, flooring and furniture.
