Selected Physico-Mechanical Properties Of Cement-Plastic Composites Of Banana Pseudo Stems Fibres

Abstract

This study investigates the viability of Banana Pseudo Stem (BPS) fibres as a reinforcement material in cement-plastic composites. BPS fibres, an abundant and lightweight lignocellulosic resource, offer promising potential due to their accessibility and eco-friendliness. However, like other natural fibers, BPS contains inhibitory substances, such as hemicelluloses and tannins, which can hinder cement setting. This research addresses these challenges through various pre-treatment methods, including water soaking and the addition of chemical accelerators. By examining untreated and treated BPS combined with plastic particles, the study evaluates the impact of BPS on composite strength, density, water absorption, and thickness swelling. Results indicate that chemical treatments and plastic additions enhance composite density and flexural strength, suggesting improved compatibility with cement. Based on these results, BPS-cement composites are recommended for indoor, non-structural applications such as insulation panels, ceiling boards, and partition walls, where the need for stability under fluctuating moisture conditions is minimized.
