An Assessment of the Sustainability of Locally Sourced Timber Specimens for use as Building Material

Abstract

This study aims to determine the sustainability of locally sourced timber as a building material in Benin City, Nigeria, by carrying out some physical and mechanical properties tests on locally sourced timber specimens (Oku, Ekki and Walnut) readily available at local sawmills in the region. These tests were done based on the British Standard code 373:1957. Proper preparation and testing of each specimen was based on standard procedures. The timber specimens were weighed, and oven dried to determine its moisture content and specific gravity/density. Compression, Tensile and Bending test were done on all specimens using the necessary machines and equipment. The data from the various test were properly recorded and analyzed. Results from the various laboratory tests were collated and comparison of the various specimens were done to determine their viability as probable building materials. From the results Ekki has the highest tensile strength (150.83N/) and compressive strength (54.6N/), while Oku which has a higher bending strength (406.25N/) of the three timber specimens. Ekki being a hardwood would be the most desirable for heavy duty construction while Walnut would be better suited for lightweight construction and furniture making
