Abstract

A 3D meso-mechanical model is introduced herein to estimate the elastic properties of concrete materials on the basis of the assumption that concrete can be considered as a three-phase material which contains cement mortar, aggregates and interfacial transition zone (ITZ). The influences of aggregate volume fraction and ITZ layer thickness on the elastic properties of concrete materials are considered in the present numerical study. It transpires that the elastic modulus increases very slightly with decreasing ITZ layer thickness and that the present model predictions are in good agreement with available experimental data and analytical results for elastic modulus. It also transpires that for a given aggregate size distribution and volume fraction the effect of aggregate shape is negligibly small in the numerical simulation.
