The article presents the results of the study of plasma chemical synthesis fullerenes using composite electrodes and the results of thermodynamic modeling Portland cement hydration. Boron was used as the additive. Boron acts as a catalyst and increases the yield of higher fullerenes C 70 in plasma chemical synthesis. The carbon soot was used as a carbon nanomodifier. Carbon nanomodifier contains fullerenes C 60 and C 70 . Thermodynamic calculations make it possible to evaluate the contribution of the carbon nanomodifier to the hydration process of Portland cement. Using thermodynamic calculations, changes in the phase composition and general properties of the system (complete enthalpy, entropy) were determined when introducing a carbon nanomodifier.
