The problem statement (relevance). The article illustrates the outcome of analytical research in the area of substantiation of organizational and managerial structures of cement companies on the basis of conducting an integral estimation of complex conditions of operation (manufacturability of mining and geological conditions of cement production, level of production and technical conditions and social conditions) and outputs (production and technical level and financial level). Integrated assessment is provided by the appropriate methodology, the purpose of which supports an increase in the objectivity, reliability and reliability of decisions in the development of technological systems of cement enterprises.Purpose: development of an enlarged flowchart of the decision-making procedure algorithm for development strategies for cement enterprises. Methods used: the work used the method of “vector norm”, based on the methodological principles of the theory of complex decision making, utility theory, game theory, qualimetry, expert survey method and other generally accepted methods and principles.Novelty. The elements of novelty include an improved method of integrated assessment of the technological structure of cement enterprises in the conditions of external and internal environments of operation.Result. The article presents an iterative algorithm and decision-making procedure for structurally selected groups of cement enterprises with the choice of a specific form of their development. The results of the work made it possible to form the key areas of training and a list of information technologies that ensure technological readiness for the implementation of the directions of digitalization in relation to cement enterprises.Practical significance: the organizational and management apparatus with the appropriate mathematical reinforcement for the selection and justification of strategies for the development of cement enterprises. The practical implication of the outcome of the study due to the possibility to increase the effectiveness of organizational-technological and managerial solutions based on the developed methodology, technique and algorithm of formation of innovative strategy of development of the mining enterprises of the cement industry. The main provisions of the work are used in the holding “EUROCEMENT” in the development and implementation of plans for the development of industrial production in the short and long term.

The share of global CO2 emissions deriving from the cement industry is about 5%. More than 50% of these are process-related and cannot be avoided. This paper addresses the application of CO2 capture technology to the cement industry. Analyses focusing on post-combustion technology for cement plants are carried out on the basis of detailed model calculations. Different heat supply variants for the regeneration of loaded wash solution were investigated. CO2 avoidance costs are in a range of 77 to 115 EUR/tCO2. The achievable CO2 avoidance rate for the investigated cases was determined to be 70% to 90%. CO2 reduction potentials were identified using CCS technology, focusing on the German cement industry as a case study. The results show that adopting carbon capture technology could lead to a significant reduction in CO2 emissions.

The Impact

The cement industry has been identified as one of the main contributors to climate change due to greenhouse gas emissions, mainly CO2. Therefore, to meet CO2 reduction targets, cement producers are working on different methods of minimizing its emission, one of which is alternative clinkers. This study assessed the impact of variations of the raw mix design, concerning the type and proportions of materials, on the formation of calcium sulphoaluminate belite-type clinkers. Various materials were used to produce raw mixes for different percentages of belite, yeeliminite, and other minerals in resultant clinkers. Computer-based theoretical mix designs were designed with different percentages of SiO2, CaO, Al2O3, Fe2O3, and SO3 and then the designed mixes were fired in a laboratory furnace at 1250oC with 20 min retention time. The resultant clinker samples were characterized with X-ray diffraction for product minerals. The quantification of minerals in every sample was carried out with Rietveld refinement. The obtained results confirmed the correlation between the mineralogy and chemical constituents in the raw mix. The C4AF percentage of the resultant clinker samples increased with an increase in Fe2O3 percentage. C4A3$ content varied with the amounts of Al2O3, SO3, and CaO. The mineral percentage of C2S in the designed mixes had a clear correlation with the constituents of SiO2 and CaO. Anhydrite percentage in the resultant minerals changed with the SO3 content in the raw mix. These results should aid in the determination of the optimum amount of chemical constituents and minerals required for the development of calcium sulphoaluminate clinker.
