The article presents experimental data on the study of the physical-mechanical properties of modified “lean” concrete. Magnesium nanospinel with mechanically activated cement and sand were used as modifiers. The prospect of modifying “lean” concrete by introducing mechanically activated parts of cement binder and fine aggregate has been established. Optimal formulations and technological conditions for manufacturing modified “lean” concrete were developed for the construction of the pavement base course in the Arctic regions.
