The article is devoted to the obtaining of activated additives and cements, to improve the quality or the obtaining of new building materials using rotary pulsation apparatus (RPA). It also considers the efficiency of the RPA. As a result the works were obtained in different activated in the RPA chemical additives for concrete from sparingly soluble in water products established distinctive features of the solutions of plasticizers and complex additives, treated in the RPA. It is shown that the preparation of concrete with the use of activated materials in the RPA to reduce labor costs in the manufacture of a product, reduce the consumption of cement, flow additives, plasticizers, water consumption, accelerate hardening and to increase strength and durability of concrete. It is noted that when changing the amount of additives in the solution and time of mechanochemical treatment, it becomes possible to control the technological parameters of concrete mixture (mobility, stiffness) and thus increase the strength of concrete. When the content of additives PDO 0.15% and activation time of 5 minutes the increase in strength was 60 kg/cm2. With increasing number of activated additives up to 1 % strength in concrete was increased, while the introduction of the same amount of additives without activation promoted a decrease in strength below without additional values.
