Surface and structural properties of the cement stone were studied using a complex nanostructured modifier. The surface properties of mixing water with surface-active substances in combination with nanoparticles of bentonite deposits of the Chechen Republic were investigated. The surface tension isotherms were presented. Compositions of complex nanomodifiers reduce surface tension of mixing water. The study on physicomechanical properties of the cement stone with complex nanomodifiers showed an increase in mechanical strength and density. Optimal concentrations of complex nano-modifiers affecting cement composites and their rheological properties were identified. The relationship between surface tension and density of the structure of cement stone was established. Based on the X-ray diffraction patterns obtained using the Selyakov-Scherer model, the sizes of crystallites were calculated.
