Abstract: A new microstructural modelling platform, CemRS (Cementitious binders Reaction
Simulator), is developed in C++ for simulating the hydration kinetics and microstructure of
cementitious systems. It takes into account different materials which could be defined as a
reacting material or which will act as a filler. CemRS can be used to implement several
existing models such as Avarami kinetics or boundary nucleation and growth etc. or it could
be used to simulate and validate original research models. It takes into account the particle
size distribution of the reactant and filler so that the effect of fineness is incorporated. The
statistical approach of storing particle sizes makes sure that the speed of the program is
increased by several orders without the need of truncation of the particle size distribution. In
this paper CemRS is used to simulate alite hydration with fillers with a new model, densified
volume growth (DVG) model which is a time dependent nucleation and growth model. The
paper demonstrates the ability of the modelling platform to simulate complicated models with
high efficiency and accuracy.
