Le, N.L.B. Stroeven, M. Sluys, L.J. Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2011-12-01 Abstract The paper introduces a novel approach to porosimetry in virtual concrete, denoted as random node structuring (RNS). The fresh state of this particulate material is produced by the DEM system HADES. Hydration simulation is a hybrid approach making use of wellknown discretization and vector methods. Particle interferences (overlap) in the dynamic packing simulation and in the hydrating system are discussed. Assessment of pore characteristics like porosity, pore size distribution and pore connectivity are described. Particularly, the last descriptor, so crucial for durability estimation, cannot be determined explicitly in experiments.
