    Abstract. Building materials with the specified operational properties currently continue to maintain their relevance. Design methods of these materials are based on the control of the structure formation of materials. One of the methods for the formation of cement composites with structural parameters providing high operational properties is the introduction of primary nano-scale materials. Such nano-scale materials are characterized by difficulties in their dispersion in a carrier medium which is especially clear for lyophobic materials. The physicochemical method of dispersion (the introduction of surfactants and ultrasonic treatment) is often used, which is of limited efficiency due to limitations associated with the reversibility of the physical adsorption of the surfactant when increasing temperature. This paper presents the results of a study of the effect on the strength of concrete of Portland cement modified with carbon nano-tubes and processed in a vortex layer apparatus. Processing in the specified apparatus was carried out to disperse carbon nano-tubes and physically activate the surface of Portland cement particles. It is established that the use of such Portland cement together with a plasticizer with the additional introduction of carbon nano-tubes makes it possible to significantly increase the compressive strength of cement composite both in the early stages of hardening, and on the 28th day of hardening in comparison with the control composition.
    Key words: carbon nano-tubes, activation, vortex layer apparatus, strength, primary nano-scale materials, Portland cement, cement composites.
