As part of the modernization of production, PJSC "Gaysky GOK" (an enterprise of the raw materials complex of UMMC) acquired for the testing laboratory of the technical control department a set of modern equipment of domestic production for testing and determining the characteristics of building materials : concrete, brick, crushed stone, cinder block, etc. The set of new equipment includes: a freezer, an automated installation for determining water resistance, as well as additional auxiliary equipment - a bath for saturation of samples, a device for accelerated determination of water resistance, cylindrical forms for testing. A testing press was also purchased to determine the tensile strength of building materials. “The new equipment will allow us to accurately determine such characteristics as frost resistance (M) and water resistance (B) in test specimens. In addition, with the help of a press, we will be able to carry out tests for both compression and bending, tensile tests of cubes, cylinders, square prisms, determine the grade by crushed stone crushing - the main characteristic of the material in the production of concrete. The higher the grade in terms of crushing, the stronger the material. This is important when creating concrete with the highest strength indicators ", - explained the head of the Testing Laboratory Olga Kodakova. Note that concrete mixes at the plant are produced in the concrete-mortar units (BRU) of the repair and construction site, underground mine and mine construction department, and to the quality of the concrete used in construction, especially underground, special requirements are imposed. “In the near future we plan to prepare a package of documents for laboratory certification, after passing which we will be able to reflect the characteristics (M and B) in the test reports, thereby fulfilling the instructions of Rostechnadzor for work on the industrial sites of PJSC "Gaysky GOK", - said the head of the technical control department Alexey Lyapin. According to experts, the financial side of the issue is no less important, because the testing of samples of concrete mixtures in a specialized testing center equipped with the necessary equipment, where samples were previously sent , cost the enterprise about 240-250 thousand rubles a year. “If we calculate the cost of purchasing equipment and compare them with the cost of testing in special centers, we can expect that the equipment will pay off within four to five years,” said Alexey Lyapin. Gaysky GOK allocated more than 1 million rubles for the purchase of new test equipment In addition to the Gaysky GOK, such enterprises of the Ural Mining and Metallurgical Company as Orenburgsky Radiator LLC (Orenburg), specializing in the development, implementation and serial production of radiator products, operate in the Orenburg Region. "Mednogorsk copper-sulfuric plant" (Mednogorsk), specializing in the production of blister copper.
