In a market economy, it becomes important to improve the organization of enterprise management and, above all, the production process, efficient use of financial, material resources and inventories. Effective management of material resources increases profits and provides the necessary investment. To maintain high profitability and liquidity, the management of current activities of enterprises, in particular inventory management plays a significant role. The categorical apparatus of material resources management at the enterprise is considered, the definition of “material resources” is generalized, the definition of "material resources management" is offered, and also the system of material resources management at the enterprise is considered. In the management of material resources at the enterprise there are 2 approaches – logistics and reengineering. The main tasks of the mechanism of management of material resources of the enterprise of building materials are defined. These are: increasing the efficiency of material resources and choosing cheap sources of funding; introduction of new production, resource-saving technologies; minimization of costs for procurement, production and marketing activities; increasing the interest of employees of all services in the effective performance of their duties; product quality management. The analysis of efficiency of use of material resources at the enterprises of building materials which has shown, that manufacture of production is rather material-intensive is carried out. This is evidenced by the share of material costs in the cost of work, and the value of the utilization factor of materials indicates the economical use of material resources in production. Reserves for improving the efficiency of material resources at construction materials enterprises have been identified. The ways of the most rational use of material resources of construction materials enterprises are offered, in particular it is improvement of a design and technology of manufacturing of products, introduction of more progressive norms of expenses of resources, use of substitute materials, and reduction of losses at stages of transportation, storage and industrial use.

Definition Of

Infrared thermography (IRT) is a technique increasingly used in building inspection. If in many applications it is sufficient to analyze the thermal patterns, others exist in which the exact determination of the surface temperature is a fundamental aspect. In these circumstances, the emissivity of the surfaces assumes special relevance, being probably the most important property in the definition of the boundary conditions. However, information on the uncertainty involved in its measurement, as well as the conditions that influence it, is scarce. This article presents an innovative contribution both to the characterization of the emissivity of various construction materials, and to the discussion of emissivity measurement procedures and the attendant uncertainty. In this sense, three experimental campaigns were carried out: T.I, preliminary tests to assess the initial conditions required for an accurate IRT measurement of the emissivity (reference tape and position of the camera); T.II, assessment of the emissivity of nine different building materials, in dry conditions, using the emissometer and the IRT and black tape methods; and T.III, assessment of the emissivity of three materials during the drying process. The results confirmed that emissivity is a crucial parameter for the accurate measurement of surface temperature. Emissivity measurements carried out with IRT (black tape method) and with the emissometer returned meaningful differences when compared with the values available in the literature. This disagreement led to surface temperature differences of up to 7 °C (emissometer versus reference values). This research also highlighted that the moisture content of the materials influences the emissivity values, with fluctuations that can be greater than 10%, and that the effect of moisture is visible even for low values of moisture content.

High requirements to ensure sanitary and hygienic working conditions and reduce harmful emissions into the environment are provided through ventilation systems equipped with efficient and economical equipment. The task of improving the air basin is to reduce the amount of harmful substances in the ambient air to the level of MPC and lower, which, with increasing volumes of ventilation and process emissions, determines the increased requirements for industrial filters. The most effective are wet devices, in which the process of gas cleaning is carried out through interaction with the liquid, most often with water. The authors developed a number of high-efficiency dust-collecting apparatuses, in which the majority of methods for contacting elements with a liquid are realized simultaneously, which determines the maximum completeness of gas purification from dusts with different physico-chemical properties. One of them is an aerohydrocyclone intended for combined simultaneous cleaning of a technological product in the form of a suspension and dusty air removed from the shelters of technological equipment. This apparatus with internal circulation of liquid, where the concentration of trapped dust in the irrigating liquid affects the efficiency of dust collection, the frequency of water replacement, the operating mode and the load of the water-slurry farm. The particulate materials of the slurry intensifies the process of dispersion, irrigating liquid and its structural viscosity, as well as the stability of the formed foam, which contributes to a more effective manifestation of various wet dust collection mechanisms.The implementation of the installation of a wet dust collector for complex cleaning in the technological line for the preparation of lime milk from the construction materials factory made it possible to reduce the concentration of dust in emissions at the maximum level of ensuring the economy of aspiration systems. The obtained results testify to the positive experience of the operation of wet dust collectors for complex cleaning in the building materials industry, and the regularities connecting the operation modes of the apparatus with the properties of trapped dusts and the features of technological processes make it possible to recommend them for use in various enterprises.

The current stage of reforming the Armed Forces of Ukraine (AF) confirms that the crisis in the country's economy has significantly affected the system of logistics of troops, which ensures its main task – to maintain the combat readiness of military units and ensure their livelihood in peacetime. The war in the east of the country and the existing state of providing troops showed the need to improve the organization and management of the process of logistical (technical, rear and medical) provision of training and combat use of the Armed Forces of Ukraine, which is currently in the phase of perspective changes and necessitates the development of a new concept of military information management and logistical flows, which will be implemented by a new, more efficient structure, called the "military logistics system". The purpose of the article is to determine the directions for the creation and accumulation of an optimal nomenclature of stocks of material resources in peacetime and their rational separation at the tactical, operational and strategic levels of management. The article describes the contents of the concepts of "logistics", "echelon", "stocking", "operational accounting". Important tasks of modern conditions of process of creation and management of stocks in the course of reforming of the Armed Forces of Ukraine are systematized; variants of the offered models of inventory management are outlined. The goal is achieved through theoretical and experimental research on volume optimization and material separation at all levels of management, which is one of the key problems of military logistics.

Because the production of aggregates for mortar and concrete is no longer sustainable, many attempts have been made to replace natural aggregates (NA) with recycled aggregates (RA) sourced from factories, recycling centers, and human activities such as construction and demolition works (C&D). This article reviews papers concerning mortars with fine RA from C&D debris, and from the by-products of the manufacturing and recycling processes of building materials. A four-step methodology based on searching, screening, clustering, and summarizing was proposed. The clustering variables were the type of aggregate, mix design parameters, tested properties, patents, and availability on the market. The number and the type of the clustering variables of each paper were analysed and compared. The results showed that the mortars were mainly characterized through their physical and mechanical properties, whereas few durability and thermal analyses were carried out. Moreover, few fine RA were sourced from the production waste of construction materials. Finally, there were no patents or products available on the market. The outcomes presented in this paper underlined the research trends that are useful to improve the knowledge on the suitability of fine RA from building-related processes in mortars.
