This article represents the results of the research of nanomodification of mineral binders involving structure formation mechanisms and gypsum binder hydration process, and thus, affecting various properties. Experiments proved that during growth, crystals partly penetrate into each other and form a three-dimensional network permeating and incorporating the entire gypsum stone into a whole body, which promotes structuring of calcium sulfate matrix and improvement in gypsum compressive strength up to 30%. Chemical functionalization of the surface of carbon nanotubes promotes a reduced sedimentation effect, allows for a more uniform nanostructure dispergation throughout the modified material volume and provides chemical interaction between the substance matrix and nanotubes.
