Abstract
The prerequisite for the research reflected in this article is the need to recycle industrial waste, such as silicon production waste – microsilica; ferroalloys production waste – refined ferrochrome slag (further – RFS); the next waste – coal-fired power plant fly ash, all these wastes can and should be used in the building materials industry. The dynamically developing construction industry requires the attention of scientists and the direction of their work to improve production technology. Thus, the article is devoted to research of influence of various small fillers (industrial wastes) available in Kazakhstan on self-compacting concrete mixes (SCC) and their rheological, physical and technical properties. By results of researches the most effective type of fine aggregate from industrial wastes, allowing to receive a high-quality SCC mix on the basis of local raw materials was revealed. The use of microsilica as compared to other industrial wastes resulted in a conglomerate with high compressive strength (SCC) at early hardening periods. In terms of economic efficiency and quality improvement, the results of the study are of practical value for manufacturers of ready-made self-compacting concrete mixtures operating in Kazakhstan.
