The present effort illustrates a semi-analytical continuum mechanical approach for approximating reaction and transport in a single C3S particles.   This simulation in one in a series of As part of a series of models being developed by the TTU team and is presently incorporated into their Population Balance formalism.1  The semi-analytical approach might be attributed to Pommersheim, who suggested a combined reaction diffusion model in 1979.2 Pommersheim, however, choose to focus on water transport, did not include a continuous phase mass balance and ignored the transport of silicate and other reactive ions.  In contrast, our model is based on H2SiO4-2 ion transport, and includes a continuous phase mass balance.  The model is demonstrated for recent physical property datasets.3
