【 摘 要 】

Mainstreaming into practice of high-tech research methods allows to conduct deeper studies of the structure of materials when changes in them occur at the molecular level. The development of technologies for obtaining materials characterized by ultrafine structure is a promising direction, since it allows to obtain materials with higher properties. Use of the products, that are waste products of silicon production, for this purpose will allow to unload the sludge dumps and reduce the environmental load. During the research, method of scanning electron microscopy was used in work, its high efficiency was confirmed due to the high speed of the analysis, short preparation time, possibility of determining the composition of the substance. Untreated wastes, as well as the products of their processing with the use of flotation, were studied, characteristics of their structure are given. Product of processing with a high content of silicon was used as a modifier of concrete. Structure of concrete was studied before and after the modification, reasons for the increase in strength were explained.
