A comparative analysis of concrete without additives and concrete samples containing molybdenum wastes was carried out. The purpose of the work is to identify the effectiveness of the metallurgical waste influence on the physicomechanical properties of concrete, the transportation from the storage site to the concrete plant, and the substantiation of their application areas. This will solve a twofold problem: to solve the problem of industrial waste (by improving the environmental status on the example of North Ossetia-Alania) and expand the range of additives used in the production of concrete. By conducting laboratory tests the physical and mechanical properties of concrete mixtures are determined. To determine the strength characteristics of concrete samples, the IM-1250M testing machine was used. The tests were carried out under the same temperature and humidity conditions. According to the results of the experiments, the samples with molybdenum-scheelite waste showed a higher result of the physicomechanical properties of concrete. As a result of experimental analysis, the influence of metallurgical industry wastes on the strength characteristics of concrete and water resistance, as well as the safety of their use in concrete mixtures, was determined. The use of waste from the metallurgical industry will save natural material, and at the same time clear large areas of these dumps. The use of waste from the metallurgical industry will save natural material and reduce transportation costs, as there are concrete plants near the dumps, which are economically feasible. Thanks to that use it is possible to clear the large territories of these dumps.
Abstract:The mechanisms for management of the building complex used and proposed to date do not always provide the required result in the assessment of the construction organization facilities. Therefore, the development of new effective methods for such an assessment is an urgent task especially in questions related to high-rise construction. The article formally sets the task of assessing the technical facilities of a construction organization. Due to the use of expert methods, the weighted values of the coefficients of local indicators for technical facilities are identified.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
