Mechel-Materials Processes Record Amount of Slag into Construction Materials

Mechel-Materials (part of Mechel Group)s grinding and mixing complex processed a record 43,000 tonnes of metallurgical waste into a mineral additive to concrete grout mixtures in July 2019. The processed amount accounts for some 40% of the blast furnace waste produced by Chelyabinsk Metallurgical Plant over the month.

The mineral additive for concrete is obtained by grinding the waste from Chelyabinsk Metallurgical Plant’s pig iron production in special mills to a fine-grained granulated slag. Additives use can reduce the cost of concrete, increase its ultimate strength, frost and water resistance, improve the surface quality.

"43,000 tonnes is not the limit for our grinding and mixing complex’s capacity. We have not been working on the market of mineral additives for concrete and mortar for very long, so the complex’s facilities are not yet operating at full load. As large orders come in, we will be able to process over 100,000 tonnes of slag a month,” Mechel-Materials’ Technical Director Ilya Malyshev commented.

The company has been gradually increasing ground granulated slag output since the grinding and mixing complex’s launch. In the first half of 2019, the company produced 120,000 tonnes of the product, which is more by a third year-on-year.

Consumers of mineral additives include concrete plants and large developers from Saint- Petersburg to Abakan. Such objects as Saint-Petersburg’s Lakhta Center and Nissan plant, Leningrad Region’s Expoforum, Abu Dhabi Plaza in Nur-Sultan (Astana), cinemas and residential districts in Moscow and Chelyabinsk’s Congress Hall were built using Mechel-Materials’ slag.
