In the bustling heart of Lagos, Nigeria, a groundbreaking study led by Dr. Eugenia Obidiegwu from the University of Lagos is turning heads in the construction industry. Her research, published in the Journal of Engineering Sciences, delves into the creation of eco-friendly ceiling boards using locally sourced materials, potentially revolutionizing the energy efficiency of buildings and reducing reliance on imported materials.
The study focuses on the characterization of ceiling boards manufactured from plaster of Paris (POP) reinforced with banana fibers (BF) and coconut shell (CS) particulates. The results are nothing short of impressive. The sample with a mixture of POP, BF, and CS demonstrated superior properties, including the lowest water absorption (2.77%), high compressive strength (7.74 MPa), least thermal conductivity (0.2157 kW/mK), and a hardness value of (23.2 HVN). These properties not only meet but exceed industry standards, making them viable for commercial use.
Dr. Obidiegwu emphasizes the significance of these findings, stating, “The potential for these materials to create high-quality, cost-effective ceiling boards is immense. Not only do they reduce environmental impact, but they also enhance energy efficiency, which is crucial for sustainable building practices.”
The implications for the energy sector are profound. Buildings account for a significant portion of global energy consumption, primarily due to heating, cooling, and lighting needs. By incorporating materials with lower thermal conductivity, such as those developed by Dr. Obidiegwu, buildings can become more energy-efficient, reducing the overall carbon footprint.
The use of banana fibers and coconut shells also addresses the pressing need for sustainable and affordable building materials. These materials are locally accessible and abundant, reducing the reliance on imported resources and supporting local economies. This approach not only promotes sustainability but also aligns with the growing trend of circular economy principles, where waste materials are repurposed into valuable products.
The study’s findings were further validated through Scanning Electron Microscopy (SEM) analysis, which confirmed the enhanced properties of the reinforced samples. This rigorous scientific approach ensures that the results are reliable and applicable to real-world scenarios.
As the construction industry continues to evolve, the integration of such innovative materials could reshape the way buildings are designed and constructed. The potential for widespread adoption of these eco-friendly ceiling boards is high, given their superior performance and cost-effectiveness. This research paves the way for future developments in sustainable building practices, encouraging other researchers and industry professionals to explore similar avenues.
Dr. Obidiegwu’s work, published in ‘Mağallaẗ Al-kūfaẗ Al-handasiyyaẗ’ which translates to ‘Journal of Engineering Sciences’, is a testament to the innovative spirit driving the construction industry towards a more sustainable future. As we look ahead, the possibilities for integrating locally sourced materials into high-performance building components are vast, promising a greener and more efficient built environment.
