a X-ray diffraction (XRD) pattern of cement hydrates in LLST and Ref. after 28 days of curing. CH, C2S, C3S, AFt, AFm corresponded to calcium hydroxide, dicalcium silicate, tricalcium silicate, ettringite and monosulfoaluminate, respectively. b–d Morphology of cement hydrates after 28 days of curing. e Hydration heat evolution within 7 days curing. f Hydration degree of LLST. Each sample was tested once. g–i Fourier Transform Infrared Spectrometer (FT-IR) spectra of Ref. and LLST after 7 and 28 days of curing.
