Review of Mesoscale Geometric Models of Concrete Materials

Concrete can be regarded as a composite material comprising aggregates, cement mortar, and an interfacial transition zone (ITZ) at the mesoscale. The mechanical properties durability of concrete are influenced by these three phases. establishment mesoscale model execution numerical simulations constitute efficacious research method. It is method to establishing executing simulations. By this method, influence aggregate shape on performance studied. This paper presents systematic review modeling methods for concrete, with focus aspects: collision detection algorithm, particle-packing algorithm. principal processes, advantages, disadvantages various discussed each aspect. concludes highlighting current challenges in concrete.
