EVALUATION OF SEDIMENTATION STABILITY OF A COMPLEX NANOADDITIVE

The sedimentation stability of a complex additive containing small doses of SiO2 nanoparticles and multilayer carbon nanotubes has been confi rmed 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.
