Tóm tắt

AbstractAmorphous silica accelerates the hydration rate of 3CaO,SiO2. This acceleration can be explained by assuming that the silica, by lowering calcium‐ and hydroxyl‐ion concentrations during the first minutes of the hydration, increases the conversion rate of a first protective hydrate layer into another less protective one.In Portland cement pastes, not only hydration of alite but also consumption of sulphate are accelerated, as judged by calorimetric experiments.
