Abstract:Based on experimental studies, a change in the characteristics of the developed concrete composition over time has been established. To determine the parameters of constructing underground structures in ground massifs, a set of studies was performed to assess the stress-strain state of the support at various periods of hardening of fast-hardening monolithic concrete. Modeling with the help of finite element method (FEM) in the software package “Lira-CAD” was carried out, the main factors determining the stress… Show more
