The article presents the procedure of interaction between the water and the particles of the cement binding agent, if subjected to high-speed processing inside an intensive mixing device that represents a hydrodynamic stirrer composed of a rotor and variable section turbines. The proposed method of modification (mechanical activation) of the cement and water suspension makes it possible to reduce the cost of concrete due to reduction of the cement consumption rate. The research of strength-related properties of the cement stone has proven that high-speed mechanical processing of the binding agent, if mixed with the water, may improve mechanical properties of concrete by 25 to 30 %.
