(57) The invention is related to nanocement production methods by modifying Portland cement, as well as to nanocement compositions. The nanocement production method involves a mechanochemical activation of dispersed grains of Portland cement in the presence of polymeric modifier, with the sodium naphthalenesulfonate content of at least 60 wt %, mineral siliceous additive containing at least 30 wt % SiO2 and gypsum, to form continuous nanoshells-capsules of 20-100 nm in thickness on Portland cement grains made of sodium naphthalenesulfonate structured by calcium cations.
