The article "Geopolymer Cement in Pavement Applications: Bridging Sustainability and Performance" by Jacob O. Ikotun, Gbenga E. Aderinto, Makungu M. Madirisha, and Valentine Y. Katte explores the potential of geopolymer cement (GPC) as a sustainable alternative to Portland cement in pavement construction. The authors highlight the environmental and performance benefits of GPC, including reduced greenhouse gas emissions, lower energy consumption, and enhanced mechanical and durability properties. They also discuss the challenges associated with GPC, such as raw material variability, the need for suitable hardeners, and the lack of standardized codes. The review integrates environmental impacts with performance metrics, providing a comprehensive evaluation of GPC's sustainability and its potential in pavement applications. The article emphasizes the importance of optimizing key ratios in GPC formation and the superior properties of GPC compared to Portland cement, making it a promising material for sustainable infrastructure development.The article "Geopolymer Cement in Pavement Applications: Bridging Sustainability and Performance" by Jacob O.
