Discrete Element Modelling of the Mechanical Behaviour of a Highly Porous Foamed Concrete
The aim of this study is to numerically investigate the effect of air void structure on the mechanical behaviour of a highly porous foamed concrete using the discrete element method (DEM). In the DEM simulation, the foamed concrete, which features high porosity and a complicated internal structure, is represented by an assembly of spherical particles randomly generated in a given space predefined by a void matrix. To simulate the cementitious phase of the foamed concrete, a cohesive-frictional model with parameters calibrated from experiments is adopted. The numerical results obtained from the validated DEM model show that the air-void structure has a significant effect on the compressive strength and the fracture of the material.
