Early Hydration Kinetics and Microstructure Development of MgO-Activated Slag at Room Temperature | Journal of Materials in Civil Engineering | Vol 35, No 1

AbstractIn this paper, active MgO was used as the alkali activator, and the early hydration kinetics and microstructure development of MgO-activated slag were explored by means of the hydration heat test, X-ray diffraction (XRD), thermogravimetry (TG-DTG), Fourier transform infrared spectroscopy (FT-IR), mercury intrusion porosimetry (MIP), and scanning electron microscopy–energy dispersive spectrometry (SEM-EDS). Three types of MgO were selected based on reaction time (R-MgO
