A Study on The Effectiveness of Coir Fiber as A Reinforcement for Gypsum Board

Abstract

Coir fiber, an easily accessible and cost-effective natural material, was studied as a reinforcement for gypsum boards. Different coir fiber and gypsum ratios were tested, and mechanical properties were evaluated. The results showed improved properties with the addition of coir fiber, particularly at a 30% ratio. However, higher fiber ratios increased water absorption and thickness swelling. Longer curing periods also enhanced mechanical properties. Coir fiber shows potential as a sustainable and affordable solution for improving construction materials, but further research is needed for optimal fiber ratios and long-term durability assessment.
