ArcelorMittal Kryvyi Rih transferred 50 million tons of metallurgical slag to the state-owned enterprise New Technologies for Road Construction. After processing into crushed slag and sand, they will be used in the construction and repair of Ukrainian roads within the framework of a large-scale state program.
According to Ukravtodor, in 2020 it is planned to use about 500 thousand cubic meters of metallurgical slag for road construction. As of mid-August, more than 100 thousand cubic meters have already been used. Basically, in Kharkov, Donetsk, Dnepropetrovsk and Zaporozhye regions. ArcelorMittal Kryvyi Rih was among the companies that provided their slag for construction work.
Andriy Babenko, Chief Project Engineer, ArcelorMittal Kryvyi Rih:
- We would like Ukravtodor and local authorities to more actively use ArcelorMittal Kryvyi Rih slags, which, by their characteristics, fully comply with the state standards of Ukraine for road construction. They can be used in road base layers and as fine and coarse aggregates for road concrete and asphalt. If the country begins to widely use metallurgical slags, then several problems can be solved at once. First, improve the quality of the road surface. Secondly, to solve the ecological problem of waste accumulation and disposal. Moreover, it is economically feasible, since roads using this technology will cost the state less than using natural materials.
ArcelorMittal Kryvyi Rih was one of the first to support the idea of building concrete roads in Ukraine using metallurgical waste. First, the company came up with an initiative to amend the regulatory framework of Ukraine, which actually legalized the construction of concrete roads using slags. Then she carried out her own experiments: a section of the road and a parking lot were built on the territory of the plant using new technology. Laboratory studies have shown that concrete made from metallurgical slags is not inferior in strength to classical concrete based on crushed granite and sand.
