    Abstract

    Early-age hydration of Ordinary Portland Cement was studied with semi-adiabatic calorimeter in the presence of limestone and calcium-silicate-hydrate (C-S-H) coated limestone. The calorimetric data was analyzed as an autocatalytic reaction. Early age hydration followed the principles of autocatalytic reaction and the rate controlling phase was the initially nucleated C-S-H. Addition of limestone did not increase it, whereas C-S-H coated limestone had a massive impact to the hydration reaction.
