Abstract
Early 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 C[3] S and C[3]A 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.
