In the heart of Nigeria, a groundbreaking study is reshaping the future of sustainable construction, with implications that could ripple through the energy sector and beyond. Researchers from Afe Babalola University, led by Paschal Chimeremeze Chiadighikaobi, have been delving into the potential of an unconventional building material: periwinkle shell concrete. Their findings, published in the journal ‘Construction Economics and Building’ (translated from ‘Ekonomi Bangunan dan Pembinaan’), promise to revolutionize how we think about construction materials and their environmental impact.
The research focuses on the suitability of granite-periwinkle shell concrete, particularly when reinforced with basalt textile. The team conducted extensive tests on concrete samples, exploring their mechanical properties, durability, and economic viability. The results are nothing short of transformative.
“One of the most exciting findings was the potential for lightweight concrete,” Chiadighikaobi explains. “Periwinkle shell concrete, especially when confined in basalt textile, showed remarkable strength and durability. This makes it an excellent candidate for lightweight constructions and load-bearing structural members.”
The study involved a meticulous analysis of 108 concrete cubes and 180 concrete cylinders, subjected to various tests including slump, density, compressive strength, split tensile, modulus of elasticity, and water absorption. The findings revealed that as the percentage of granite decreased and periwinkle shells increased, the workability, density, and mechanical properties of the concrete also decreased. However, the concrete’s strength proved to be more than adequate for structural use, especially when reinforced with basalt textile.
“This type of concrete is not only economical but also easy to manage in construction,” Chiadighikaobi notes. “It aligns perfectly with the sustainable development goals of creating sustainable cities and communities, and promoting responsible production and consumption.”
The implications for the energy sector are profound. Lightweight, durable construction materials can significantly reduce the carbon footprint of building projects, aligning with the growing demand for sustainable practices. As the world shifts towards greener energy solutions, the construction industry must follow suit. Periwinkle shell concrete offers a viable, eco-friendly alternative that could shape the future of sustainable construction.
The research published in ‘Construction Economics and Building’ opens the door to a new era of sustainable building practices. As the construction industry continues to evolve, the integration of innovative materials like periwinkle shell concrete could become a cornerstone of sustainable development. The study by Chiadighikaobi and his team at Afe Babalola University is a testament to the power of innovation and the potential for transformative change in the construction sector. As we look to the future, the possibilities are as vast as they are exciting.
