Abstract: Cement hydration is an extensive area of research because of the complex chemistry involved and also the multi scale nature of the hydration products. Several attempts to model the dissolution of cement grains and the formation of the main hydration product calcium silicate hydrate (C-S-H) gel as a space filling nucleation and growth process could be found in the literature. An earlier work by some of the authors of this article introduced a Monte Carlo model which was capable of explaining the kinetics of the hydration process at early ages.
Relying on the colloidal approach put forward by Jennings and employing a nucleation and growth of 5nm sized C-S-H particles, the early age kinetics was described. We extended this model to take in to account the effect of water to cement mass ratio and the effect of external C-S-H seeds.
