Комплексная добавка на основе углеродных нанотрубок и микрокремнезема для модификации газосиликата автоклавного твердения

Abstract

Complex additive based on carbon nanotubes and silica fume for modifying autoclaved aerated gas silicate The influence of complex additives based on dispersion of multi-walled carbon nanotubes (MWCNTs) in combination with MK- 85 silica fume on the structure and properties of autoclaved aerated gas silicate has been studied. Physical and chemical studies of the additive have shown its activity towards calcium hydroxide, which has improved the mechanical properties of autoclaved aerated concrete. The conducted studies of physical and mechanical properties (compressive strength and thermal conductivity) have shown the dependence of the properties of aerated concrete on the ratio of the used complex additives and technologies of their adding in the process of producing mortars.
