Abstract
carbon nanotubes (MWCNTs) in the range of 0.00004–0.000006 wt. % of the mass of cement on the structure and mechanical properties of concrete was demonstrated. A correlation was found between an increase in the mechanical strength of concrete by 56 % with changes in the structure of the cement stone, at which the proportion of crystals of calcium hydroaluminate, calcium hydrosulfoaluminate and type 14A tobermorite increases significantly. The results obtained lay the foundations for the development of a technology for the industrial production of complex additives in concrete with a combination of nanoparticles (MWCNT + SiO2), which make it possible to improve the mechanical and physical characteristics of concrete and increase its durability.
