Design of High-Strength and Ultra-High-Strength Alkali-Activated Materials Based on Physico-Chemical Principles

Alkali-activated materials (AAMs) represent a promising alternative to conventional cementitious binders, particularly due to their potential to achieve high to ultra-high mechanical performance while reducing the environmental impact. The proposed research focuses on the rational design of AAMs aimed at achieving high and ultra-high strength based on an in-depth understanding of the underlying physico-chemical processes governing alkali activation. The research will investigate the relationships between system composition (precursor type, activator composition), reaction kinetics, micro- and nanostructural development, and the resulting mechanical properties. The experimental approach will involve advanced characterization techniques and comprehensive analysis of material structure and performance. Based on the obtained insights, design principles will be formulated to optimize microstructure and maximize the mechanical performance of AAMs.
