These materials were characterized using attenuated total reflectance Fourier transform infrared spectroscopy, infrared Raman spectroscopy, energy-dispersive X-ray spectroscopy, the X-ray photoelectron spectroscopy, etc. The differences found in the primary structure of SiO2 particles (amorphous vs crystalline) and the impurities content were considered as determinative factors for particles’ surface modification and use in mortar or concrete. These results provide a fundamental background that contributes to a better understanding and explanation of the interaction reactions of Si-based secondary raw materials used as fillers in alkali-activated cement-based composite materials.
