In an innovative stride towards sustainable construction, recent research led by Hassan Abdullahi Maikano from the School of Civil Engineering at Linton University College, Malaysia, has unveiled the promising potential of palm kernel shells (PKS) and quarry dust (QD) as cost-effective substitutes for traditional sand and gravel in concrete production. This groundbreaking study, published in the ABUAD Journal of Engineering Research and Development, highlights a significant opportunity for the construction industry to embrace eco-friendly materials while simultaneously reducing costs.
The research meticulously examined how varying proportions of PKS and QD affect key concrete properties such as workability, density, water absorption, and mechanical strength. Notably, while increasing the content of these alternative aggregates tends to decrease workability and density, it simultaneously enhances water absorption and, in some instances, boosts mechanical strength. “Our findings suggest that a blend of 5% PKS and 20% QD strikes an optimal balance, achieving an impressive cost reduction of 18.2% compared to conventional aggregates,” Maikano emphasizes.
This cost-efficient approach not only alleviates the financial burden on construction projects but also champions sustainability by utilizing waste materials that are abundant in regions with palm oil production and quarrying activities. By replacing traditional aggregates with PKS and QD, the industry can significantly reduce reliance on natural resources, paving the way for more responsible waste management practices.
Furthermore, the research indicates that quarry dust may serve as a more effective replacement material than palm kernel shells due to its superior impact on concrete strength. This insight could lead to a paradigm shift in material selection for construction, urging suppliers and contractors to consider these sustainable options seriously.
As the construction sector grapples with rising material costs and environmental concerns, this research serves as a beacon of hope. It not only opens doors for innovative mix designs but also aligns with global trends towards greener building practices. “The adoption of such alternative materials can redefine concrete production, making it more sustainable and economically viable,” Maikano adds.
The implications of this study extend beyond mere cost savings; they signal a transformative movement within the construction industry that prioritizes sustainability without sacrificing performance. By integrating PKS and QD into concrete mixes, the sector could witness enhanced durability and resilience, essential qualities in today’s ever-evolving construction landscape.
