We will create a multiscale framework to model salt-precipitation, evaporation, and bio-mineralization in porous media. Importantly, this allows for analyzing precipitation kinetics and structure on a molecular scale by using all-atom simulations and machine-learned coarse-grained models (WP 1) to inform a lattice-Boltzmann-Electrokinetic model for evaporation-precipitation and pH-responsive calcite formation (WP 2). The biofilm model will be extended to include nutrient transport and enzymatic activity for simulating microbially induced calcite precipitation, thus allowing for optimizing bio-cement granule production parameters (WP 3).
