Abstract
In the article it is justified that composite building materials refer to self-organizing systems in accordance with all indications. Considering such properties of self-organizing systems as openness and dynamism, which make them «sensitive» to external influences, it is very effective to use various activation methods for the purpose of regulating the properties of materials. A detailed analysis of the literature review on the types and methods of activation of raw materials and a solution mixture is given. Particular attention is paid to the acoustic treatment of aqueous and cement-water solutions. Ultrasonic treatment allows the dispersion of particles of the mixture, as well as intensification of the processes of mixing and homogenization. The results of experimental studies are presented that indicate the influence of acoustic energy supplied during the period of the formation of foam concrete on the change of its physical and mechanical properties. The prospects are shown and the ways of further research are outlined.
