In the quest for sustainable and cost-effective construction materials, a groundbreaking study led by KOTUN MUSTAPHA OLANREWAJU has shed new light on the potential of oil palm broom fibres (OPBF) as a reinforcement for concrete. The research, published in the Journal of Engineering Studies and Research, explores how these natural fibres can enhance the mechanical properties of concrete, offering a promising avenue for the energy sector and beyond.
The study delves into the use of OPBF in structural concrete, focusing on the impact of alkali treatment on the fibres’ durability and strength. The fibres were subjected to varying concentrations of sodium hydroxide (4%, 6%, 8%, and 10%) and different treatment durations (1 hour, 2 hours, 8 hours, and 24 hours). The goal was to determine the optimal conditions for enhancing the flexural strength of concrete beams reinforced with these fibres.
The results were compelling. The treated OPBF, particularly those treated with 6% NaOH for 1 hour, significantly improved the flexural strength of the concrete. This finding is a game-changer for the construction industry, especially in regions where oil palm is abundant. “The treated OPBF with alkalization improves the flexural strength of concrete beam at a concentration of 6 % NaOH for a duration of 1hr,” OLANREWAJU noted, highlighting the potential for low-cost, eco-friendly construction materials.
The implications for the energy sector are substantial. As the demand for sustainable energy solutions grows, so does the need for durable, cost-effective construction materials. The use of OPBF in concrete could revolutionize the building of energy infrastructure, from wind farms to solar installations, by providing a more sustainable and economical alternative to traditional reinforcement materials.
The study also revealed that the treated fibres had a higher rate of water absorption compared to untreated fibres, which could affect their long-term durability. However, the dispersed cavities observed in the SEM images of the OPBF cross-section suggest that the fibres’ structure remains intact, ensuring their effectiveness as a reinforcement material.
The research by OLANREWAJU and his team opens up new possibilities for the use of natural fibres in construction. As the world moves towards more sustainable practices, the integration of OPBF in concrete could pave the way for innovative and environmentally friendly building solutions. The findings, published in the Journal of Engineering Studies and Research, provide a solid foundation for further research and development in this area. The study’s insights could shape future developments in the field, driving the construction industry towards a more sustainable and cost-effective future.
