Incorporation of calcium-rich fly ash enhances the long-term durability and sulfate resistance of cementitious systems.
Mechanical testing showed initial strength reductions, with later improvements driven by secondary reactions consuming portlandite.
Electrochemical monitoring revealed markedly lower reinforcement corrosion rates, suggesting better overall durability.
Bond tests indicated a transition to a more ductile response, benefiting applications in repair and construction.
