Experimental Study and Numerical Simulation of the Development of the Microstructure and Permeability of Cementitious Materials

The aim of this thesis was to investigate and to simulate the development of the microstructure, porosity and permeability in hardening cement-based materials. Based on experimental information and the cement hydration model HYMOSTRUC, the microstructural details including porosity, connectivity of pores and pore size distribution were characterized. A network permeability model was built up based on the simulated microstructure and validated with the experiments.
