Study on Hydration Mechanism of Slag Activated by Alkaline

Abstract:

By measuring the heat of hydration during the hydration of water quenched slag produced by molten iron boiler water, combined with water quenching measurements, infrared spectroscopy, X-ray diffraction, differential thermal analysis and electron microscopy observation and analysis, the authors argued that the type of water quenched slag is a kind of potential activity of the vitreous structure. Protective film theory (the surface layer of silicon-oxygen network) is put forward. Therefore, the slag hydration must be excited in the activator destruction of this layer of film, and this hydration process can be divided into three stages. They are: the early hydration of sodium silicate hardening; slag’s surface structural damage and the network structure dissolution and disperse in the early hydration reaction phase; the acceleration of hydration reactions and stable phase in the late.
