Popis:	The article is devoted to the selection of optimal parameters of a chemically hardening mixture based on quartz sand with a liquid‑glass binder cured with liquid esters for the production of castings of heavy machinery, machine tools and shut‑off valves. The analysis of the quality of molding sands of three brands, of different origin, was carried out. The strength characteristics of mixtures of various compositions are studied. Based on the data obtained, conclusions are drawn about the optimal characteristics of sand and the amount of binder additive. The compositions of easily knocked‑out environmentally friendly liquid‑glass mixtures cured with esters for the manufacture of molds and rods in machine‑tool armature construction are recommended.
