Abstract: Physical and mechanical properties of cement-based materials are directly linked to their microstructure. in recent year microstructure modelling platforms have emerged(e.g.HYMOSTRUC,CEMHYD3D and μic) which simulate the evolution of microstructure of cement paste during hydration. microstuctures can be utilized to obtain physical and mechanical properties. However due to underlying assumptions in these models, morphologically different microstructures (different pore connectivity, pore size andpercolation thresholds) are obtained from these platforms for same water-cement ratio and cement composition. The question then arieses whether the estimations of properties of cementpaste using these microstructures is reliable or not. In these paper we discuss issues related to achieving reliable predictions of the transport properties using microstructures generated from these platforms.
