Abstract: This paper aims to present an example of the benchmark numerical simulation for cement- based materials in Micro-level within COST Action 1404 by using numerical tools developed at Delft University of Technology. In the benchmark, the Portland cement paste with water- to-cement ratio 0.4 at temperature 20 oC was used. The input parameters included the chemical and mineral composition, the density, the specific surface and the particle size distribution of Portland cement. The hydration process and microstructure development of Portland cement paste were simulated with HYMOSTRUC3D model. The water permeability and chloride diffusivity of Portland cement paste were simulated with Lattice Boltzmann method based on simulated microstructure. The mechanical properties of Portland cement paste, including load-displacement curve, elastic modulus, tensile strength and cracking pattern were simulated with a 3D lattice finite element fracture model.
