An experimental procedure of synthesis of complex additive based on nano-sized particles SiO2 obtained by activation of microsilica in the of vortex layer apparatus in the presence of superplasticizer of the «Relamix type 2» brand is proposed. The kinetics of hydration and the microstructure features of the modified cement stone have been studied by X-ray diffraction and scanning probe microscopy. There has been established the acceleration of hydration processes and the change in the modified cement stone structure compared with the reference system.
