A quantitative weathering study of wood surfaces modified by chromium VI and iron III compounds
1989 - IRG/WP 2330
Thin veneers of Pinus radiata were treated with dilute aqueous solutions of chromium VI and iron III compounds and exposed to natural weathering for 35 days. Zero-span tensile strength and weight losses of treated veneers were compared with losses observed in untreated specimens In a study designed to demonstrate the applicability of strength and weight loss measurements to the rapid quantitative ...

Detection of methanogenic bacteria in mining timber
1988 - IRG/WP 1352
Methane explosions in gold mines have been attributed to spontaneous ignition of methane/air mixtures. Biogenesis of methane in the heartwood of diseased trees has been shown, but never in timber in service. Studies were therefore undertaken to establish whether methanogens were present in wooden pit props. Core samples were removed by Pressler increment borer from props in disused areas 2,600 m d...
