The bio-mechanical properties of coco wood applied with Neem extracts: a potential preservative for sustainable building in Marinduque, Philippines

Abstract

Abstract The purpose of this study was to develop an organic wood preservative from the liquid extract of Neem tree (Azadirachta indica). This product has the potential in controlling the fast deterioration of coco wood by extracting liquid from fruits with seeds and leaves of Neem tree. Effectiveness as wood preservative was investigated for termite repellency, water absorption, and tangential swelling following American Society for Testing and Materials methods such as D-3345–74, D-4442-92, and D-4446-06, respectively. The study revealed that wood samples with Neem extracts have favorable effects in preserving coco wood. It was also observed that extract from Neem leaves and fruits with seeds has no significant difference in terms of effectiveness on wood preservation displayed and coco wood physical characterization. The majority of the results were commensurate to gear on an affirmative finding to conclude that the liquid extract from Neem can be used and further explored as an effective material for wood preservation.
