Heavy concrete on cement with slag of low-carbon ferrochrome

Abstract

This research work is aimed to determinate a possibility of stabilization of a low-carbon ferrochrome slag into a dry slag and further recycling it into a commercial product. Research was done with petrographic analysis of the structure of the artificial stone. The influence of a commercial product on constructional and technical properties of concrete and concrete mixture was determined according to the requirements of the standards for this product. As the result of the investigations of low-carbon ferrochrome slag the common regularities of formation of minerals of CaO-SiO2-Al2O3-MgO-Cr2O3 system in artificial stone were determined. Depending on the conditions of stabilization, the main minerals, formed during industrial stabilization of slag, and the structure of stabilized slag were studied in detail. The laboratory research was done and as the result new common influence patterns of fine powdered stabilized slag upon the properties of concrete mixes and concrete were reached.
