Advancing Self-compacting Eco-Friendly Green Composites: A Parametric Review of Geopolymer-Based Innovations
摘要
The increasing demand for sustainable infrastructure has intensified research into eco-friendly alternatives to ordinary Portland cement (OPC), whose production is associated with significant CO2 emissions and resource depletion. Among these alternatives, self-compacting geopolymer concrete (SCGP) has emerged as a promising material due to its superior mechanical performance, environmental benefits, and adaptability in construction applications. This review consolidates recent advancements in SCGP, focusing on its chemistry, fabrication methods, and the influence of key parameters such as alkaline activators, curing regimes, aggregate properties, binder content, alkali-to-binder ratio, alkali solution ratios, fineness, and molarity. A systematic survey of the literature from leading scientific databases highlights the critical role of parametric control in enhancing both the fresh and hardened state properties of SCGP. The review also outlines the potential of industrial by-products in reducing dependency on OPC while improving performance characteristics. Findings indicate that optimal combinations of alkaline activators, fineness, and curing conditions yield SCGP with superior workability, compressive strength, and durability compared to conventional mixes. Overall, this study provides a comprehensive framework for understanding the parametric influences on SCGP, reinforcing its potential as a sustainable and high-performance solution for future construction needs.
