Microstructure-based modeling of permeability of cementitious materials using multiple-relaxation-time lattice Boltzmann method

► Permeability of cementitious materials was modeled via MRT lattice Boltzmann method. ► 3D microstructures of cement paste at various curing ages were generated. ► Relationship between permeability and microstructure characteristics was analyzed. ► The simulations were verified with the experimental results from literature. ► The permeability and effective porosity is highly correlated.
