The study of the dependence of mechanical properties and fracture of water-saturated high-strength concrete on the parameters of pore structure

The study of the dependence of mechanical properties and fracture of water-saturated high-strength concrete on the parameters of pore structure

Based on the hybrid numerical method, namely, the hybrid method of movable cellular automata, we developed a computer-based two-scale mechanical model of heavy water-saturated concrete. The model takes into account the content of the liquid phase and its redistribution in networks of microscopic and...
