A percolation-based micromechanical model for elastic stiffness and conductivity of foam concrete

Void morphology effect on percolation and even physico-mechanical performance of foam concrete is great interest in the evaluation service-life civil hydraulic infrastructures. For experiments, it a huge challenge to quantify threshold voids affected by their morphologies, dependence elastic modulus conductivity void configurations. In this work, we focus prolate spheroidal morphologies with aspect ratios 2.5 2, following microscopic measurements reported literature. A numerical framework developed capture characterized critical porosity both morphological types. verification purpose, Measurement spherical using present as benchmark compared against monodisperse overlapping spheres Furthermore, work proposes simple powerful percolation-based micromechanical model for precisely predicting effective thermal concrete. It can be convinced general elucidate intrinsic relationship properties The capable tailoring physical mechanical through configuration enable design multifunctional applications.
