A Mixture Design for Fiber Reinforced Gypsum Board utilizing Human Hair and Coconut Fiber

Numerous studies have demonstrated the significant environmental impact of human hair and coconut husk as pollutants. This highlights an opportunity for researchers to investigate these materials as alternative fiber reinforcement, focusing on their mechanical properties (dry density, flexural strength, and water absorption) while addressing environmental concerns associated with traditional materials. This study aims to explore the potential of using human hair and coconut fiber as reinforcements in gypsum boards, employing a research and development approach to design and fabricate prototypes. Following data gathering and analysis, human hair and coconut husk are collected and used as aggregates for fabricating fiber-reinforced gypsum boards. The boards are cured for 2-4 hours and dried for 3-4 days. The study examines the effects of varying fiber proportions on the physical and mechanical properties of the gypsum board, identifying optimal combinations that enhance strength and durability. Subsequently, the fabricated gypsum boards are tested at registered engineering laboratories and compared to ASTM standards. The study concludes that the developed mixture design offers a feasible way to produce fiber-reinforced gypsum boards with suitable dry density, flexural strength, and water absorption, contributing to sustainable development in construction materials. Utilizing human hair and coconut fiber in gypsum board formulations enhances its sustainability and cost-effectiveness compared to conventional reinforcements. The optimum ratio of coconut fiber to human hair is 180g and 120g, respectively, resulting in gypsum plaster formulations with favorable qualities such as low density, high flexural value, and reduced water absorption. This research indicates the potential for human hair and coconut fiber to serve as sustainable alternatives in the building industry..
