description: This work is devoted to the development of the composition of liquid-glass chemically hardening mixtures on a chromite filler and the study of the process of forming the strength of these mixtures. Tasks that were solved during the study:the study of the technical characteristics of chromite sand of various brands, the selection of a brand of sand with favorable indicators, the study of a liquid-glass chemically hardening mixture made using chromite sand of the selected supplier, testing of molding mixtures for strength, crumbling, gas permeability, analysis of the results obtained. Five samples of chromite sand of various grades were studied to determine the granulometric composition, humidity and uniformity. Based on the data obtained, one sample of chromite sand was selected, from which samples were made for subsequent tests for humidity, gas permeability and compressive strength. Based on the conducted studies, it was assumed that sample No. 5-chromite sand has the best strength characteristics. Manufacturer EK Company. Supplier D with an amount of liquid glass equal to 3.5 percent.
