ABSTRACT
Our goal is to understand extremely polydisperse media where the size distribution follows a truncated power law where the polydispersity, the ratio between largest and smallest particle, ranges over four decades. These media are comparable to modern high performance concrete (HPC). To reduce the enormous number of particles in the simulation we develop a self-consistent model where we only simulate the first decade. All smaller particles are handled through so called soft-particles. A soft-particle contains particles of the next decade and again a set of soft-particles containing the remaining decades. For the last decade we only have “normal” particles in the soft-particles.
