Abstract:
The increasing environmental impact of traditional cement production necessitates the exploration of sustainable alternatives in construction materials. This paper investigates corncob ash (CCA), an agro-waste by-product, as a
viable substitute for cement in several construction and building material applications such as concrete, masonry,
geopolymer materials, and soil stabilization. A comprehensive review of existing literature reveals that CCA
enhances the mechanical properties of these materials, such as compressive strength and durability, and
significantly reduces the carbon footprint associated with conventional cement production. The findings indicate
that incorporating CCA improves workability and resistance to aggressive environmental conditions, positioning
it as a promising material for sustainable construction. Furthermore, the paper identifies gaps in current research,
particularly concerning long-term performance and standardization of testing methods. Future research directions
are proposed, including optimization of processing techniques, life cycle assessments, and real-world
applications, to fully leverage the potential of CCA in promoting environmentally friendly construction practices.
Overall, this study underscores the critical role of CCA in advancing sustainability within the construction
industry.
