N2 - A lattice Boltzmann based pore scale reactive transport model is used with a reactive term computed using a simplified reaction model for portlandite system. This simplified reaction model is pre-computed using full geochemical model. This approach is computationally more efficient and was found to be reasonably accurate for pore-scale simulation when compared to full geochemical model. To explore the role of pore network characteristics on transport properties and the calcium leaching front, the developed approach was applied to a series of simulations on randomly simulated pore structure.
