Cover Story: Alkali-activated binders (AABs) are developed by dry mixing of solid reagents and industrial-waste-based supplementary cementitious materials (SCMs) as precursors under ambient conditions. The effects of binary and ternary combinations/proportions of SCMs, two types of solid reagents, fundamental chemical ratios (SiO2/Al2O3, Na2O/SiO2, CaO/SiO2, and Na2O/Al2O3), and the incorporation of polyvinyl alcohol (PVA) fibers on the fresh-state and hardened characteristics of sixteen AABs are investigated to assess their performance for finding suitable mix compositions. The addition of 2% v/v PVA fibers to binder compositions did not significantly impact the compressive strengths. However, it facilitated the mitigation of shrinkage/expansion strains through micro-confinement in both binary and ternary binders. View this paper.
