Hydration reactions in portland cement-silica fume blends
AbstractEarly hydration reactions of portland cement-silica fume blends were followed by conduction calorimetry, Ca(OH)2 estimation, and later reactions by Ca(OH)2 and non-evaporable water contents. Silica fume accelerated both C3S and C3A hydration in the first few hours. At longer periods pastes of blends hydrated to a greater extent than mortars, possibly because sand acted as a Ca(OH)2 sink in the mortars.
