Numerical Study of the Mechanical Behavior of Polymer Concrete

Hawachi I

Polymer concretes (PCs) represent a good alternative to traditional cementitious materials in the field of new construction. In fact, PCs exhibit high compressive strength and ultimate compressive strain values, as well as good chemical resistance. Within the context of these benefits, this paper presents a study on the behavior of polymer concrete using a mechanical model recently developed by the authors. A 2D model is constructed in which aggregates are modeled by random distributed polygon. Compressive testing of the PC is firstly carried out to provide experimental benchmark for validation of the proposed numerical model a numerical simulation of the model is then performed using COMSOL software and the compressive and bending stress-strain curves are obtained.
