Performance based simulation of pervious concrete using discrete element method

Abstract

Pervious concrete is a special type of concrete that differs from ordinary concrete by its highly porous nature, which is why this type of discrete material can not be modelled using the Finite Element Method (FEM). Behaviour of pervious concrete samples with different aggregate sizes and void ratios is simulated in the paper, using the Particle Flow Code (PFC) software, which is based on the discrete element method (DEM). The PFC software is used to simulate various experimental results obtained on high paste content pervious concrete samples.
