Kalmykova Y. Reducing the anthropogenic influence on the environment by recycling of dump blast furnace slag

The object of study is the environmental pollution by dump blast furnace slag. The aim is the decrease of the anthropogenic load on the environment by dump blast furnace slag recycling in the production of building materials. The research methods: X-ray analysis; electron probe microanalysis; petrographic analysis; gamma-spectrometry analysis; atomic absorption spectrophotometry method; methods of mathematical statistics, mathematical modeling. Theoretical and practical results: the advisability of metallurgical industry waste through recycling into building materials has been confirmed. The technologies of use of dump blast furnace slag utilization have been developed and implemented at the enterprise, that allows to carry out the recycling of production wastes, to receive the economic effect and to reduce the negative impact on the environment components. The novelty: the reduction of anthropogenic impact of dump blast furnace slag on the environment during processing by reducing the volume of slag dumps has been scientifically proved for the first time, the criteria for the safe use of the resource and radiation safety dump blast furnace slag fractions in the production of binders have been theoretically substantiated and experimentally determined, the scientific foundations of the technologies of dump blast furnace slag fractions use in the production of environmental safety slag-alkaline binders have been studied; the scientific understanding of the environmental assessment of pollution near the blast-furnace slag dumps have been improved; the principal technological schemes for the creation of low-waste radiation-safe technologies of slag Portland cement and slag-alkaline binder's production have been further developed. The degree of implementation: at the Scientific and Production Company "MATECO" and into the educational process at Kharkiv National Automobile and Highway University during the training of bachelors in directions: 6.040106 - "Ecology, environment and balanced natural resources application" 6.060101 - "Building." The scope of application: the results can be applied at enterprises for the production of building materials with the use of dump blast furnace slag.
