The low pozzolanic activity of fly ash (FA) leads to reduced early-age strength in high-volume FA cement systems (HVFAC). While the individual addition of triethanolamine (TEA) or nano-silica (NS) can enhance the mechanical properties of HVFAC, the synergistic effect of their combined incorporation remains unclear. This study investigates the synergistic effect of TEA and NS on the early hydration process and the mechanism of later-stage strength enhancement in HVFAC, using methods including compressive strength testing, isothermal calorimetry, the hydration kinetics model (K-D), TG, Rietveld-...
