The paper deals with the issues of technology of binding silicate materials with the use of mineral waste from the processing of petroleum bituminous rocks (PBR) – optimization of the ratio of raw components of the mixture of binders, development of optimal technological parameters for their production. The optimal compositions of binders were studied using waste from the processing of PBR as an activating component of cement. The influence of mechanic and chemical activation on the change in the acid-base parameters of the suspension from the crushed material was revealed. The effect of the content of additives on the degree of hydration was studied. The influence of the hardening conditions on the strength of the binder with additives of waste from the processing of PBR was studied. As a result of the experimental work carried out, technological processes for the production of binders based on waste from the processing of PBR were justified and developed. The optimal ratio of the mixture of waste from the processing of PBR with cement and the technological parameters that allow ensuring the optimal grade of the cement-sand binder are found. Silicate materials based on it have high physical and mechanical properties, meet regulatory requirements and have high resistance under operating conditions.

The scientific work “Research of recirculation systems and air recovery systems” is devoted to the analysis and selection of the most optimum ventilation systems that will reduce the cost of published products by reducing energy consumption. The purpose of this work is to discover and experimentally study the characteristics that affect the use of thermal and electric energy by ventilation systems and air heating in the industry, as well as to create solutions that allow to achieve a decrease in the consumption of fuel and energy resources for these systems. The relevance of the work is to reduce the cost of manufactured products and increase their own competitiveness by saving consumed energy resources. In this regard, the development of completely new solutions focused on the economic efficiency of electrical and thermal energy in ventilation and heating systems in various industries, with a simultaneous increase in sanitary hygienic efficiency, today is an urgent task of solving the problem and has economic national importance.
