Durability and strength properties of Triplochiton scleroxylon wood treated with Thevitia peruviana seed oil after fungal attack
The effect of Thevitia peruviana seed oil treatment on weight loss and compressive strength of decayed sap wood of Triplochiton scleroxylon was investigated. The phytochemical analysis of methanolic extracted T. peruviana seed oil was determined qualitatively and quantitatively after which five conc...
