Abstract
The analysis of the production of broken stone materials shows that the processing enterprises of this product have problems with the storage of waste product. The dumps of waste cover huge areas of land suitable for agriculture use. The accumulation of waste also affects the environment. Its accumulation occurs due to the imperfect technology of waste products recycling. Granite screenings is the waste of this production. The introduction of modern waste recycling technologies allows to get washed sand, which becomes a competitive product. The paper analyzes the granulometric composition of different types of sand, compares granulometric composition of different types of sand and the directions of use of sand in various industries, also it highlights construction and road works. In general, the paper is dedicated to the production of granite sand. The physical and mechanical properties of granite sand and its fractional composition are described. A comparison of the granulometric composition of granite sand with an «ideal» granulometric curve of filler with a grain size of 2.5 mm (by Fuller) is made. The analysis shows that the curve for washed sand closely approximates to the «ideal» curve. This fact indicates that granite sand has a wide range of applications as filler for production plaster and building mortars. According to quality indicators, washed sand meets European quality standards. The widespread use of granite screenings makes it possible to reduce the environmental impact and improve the technical and economic performance of enterprises that are engaged in mining of broken stone.
