| Abstract | The influence of different additions (dry powders or solutions of compounds industrially available) on the early hydration kinetics of ordinary Portland cement is investigated by isothermal calorimetry. The results establish that the additions of Master X-SEED100, calcium nitrate tetrahydrate, calcium chloride and a synthetic solution of hydrated Portland cement can highly accelerate, even at low concentration, the hydration kinetics of Portland cement. Using higher weight ratios, fumed silica, titanium dioxide and precipitated calcium carbonate accelerate moderately the hydration. Moreover, the nanoparticles made of iron or iron oxide and the activated charcoal filler do not show any accelerating effect. (C) 2016 Elsevier Ltd. All rights reserved. |
