Although heat-cured concrete (HCC) has received extensive research interests in recent years, it still suffers from problems including coarsened microstructure and low cement hydration degrees, which limited its application. Some of these problems can be solved by internal curing method resulting in low early strength of HCC and low-production efficiency. This study addressed this issue by activating the aluminosilicate internal curing agent (lightweight fine aggregate, LWFA) with triisopropanolamine (TIPA). More Al3+ and Fe3+ ions were dissolved from LWFA by TIPA, which assisted the formation of hydrates with cement ions in interfacial transition zone (ITZ), and enhanced the d. of ITZ in the early stage. The introduction of TIPA increased the early compressive strength of HCC, by ∼15.3%, 25.9%, and 28.0%, resp. for the cement cured for 1, 3, and 7 days compared with control samples. Moreover, the results of rapid chloride migration and water absorption depth also suggested that coupling the aluminosilicate internal curing agent with TIPA improved the pore structure of HCC.
