The sedimentation stability of a complex additive containing small doses of SiO2 nanoparticles and multilayer carbon nanotubes has been confirmed experimentally. It has been revealed that the additive remains sedimentationally stable after mechanical mixing and retains its properties for at least 3 months after preparation. Additional mixing with tempering water at the stage of its introduction into a concrete mixture does not contradict the traditional options for the introduction of chemical additives.
