DEVELOPMENT OF SPECIAL MIXTURE COMPOSITION FOR BUILDING MATERIALS BASED ON ANHYDRITE BINDERS

The technology of obtaining hydrofluoric acid and the peculiarities of its production are studied in the work, as well as physical and chemical studies of the properties of the waste. Activators accelerating the hardening of anhydrite binder were selected. The process of utilization of fluorohydrite waste from the production of hydrofluoric acid of JSC «Ulba Metallurgical Plant» was investigated and anhydrite anhydrite binder without firing with setting time of 30 min was obtained. On the basis of the received data the technological scheme of manufacturing of products from anhydrite binder is developed. The efficiency of the adopted technological scheme is confirmed experimentally. Also the given work is directed on studying of possibility of complex use of secondary and technogenic raw materials of Ulba Metallurgical Plant, which in the end acquires value not only important reserve of increase of efficiency of manufacture, economic benefit, reduction of irrational alienation of land resources, but also protection from pollution of water and air basin as questions of ecological policy of JSC «UMP» at present are actual. At research of characteristic of technogenic wastes of production of hydrofluoric acid, their potential suitability for manufacture of anhydrite binder and building materials on its bases has been shown. The influence of limestone dispersibility on the completeness of the neutralization reaction has been established.
