Global Slag News

Russia: Eurocement subsidiary Belgorodsky Cement has announced the start of commercial production of a new CEM-III slag Portland cement. The company says that the cement is highly water and frost resistant and suitable for use in the construction of massive ground and underground structures. Belgorodsky Cement director general Eduard Androsov said, “We offer our customers an individual approach to solving construction problems and guarantee a stable supply of high quality products in the required volumes and within strictly defined deadlines.”

Belgium: The World Steel Association (WSA) forecasts that total global steel consumption in 2020 will be 1.65Bnt, down by 6.4% year-on-year from 1.77Bnt in 2019, due to the impacts of the coronavirus outbreak on steel-intensive industries. The WSA estimated that demand will decline by 17% in developed countries, with the steepest falls in Japan, South Korea and the US, and by 18% in India. China’s steel consumption is expected to rise by 1% due to increased infrastructure spending and a swift post-coronavirus recovery. Construction, a mostly seasonal sector, had already reached full productivity in April 2020.

The WSA expects steel demand to increase by 3.8% year-on-year in 2021 to 1.72Bnt globally. The sharpest recovery is expected to be in developing countries, where the WSA says that total demand will increase by 9.2%, following a fall of 11.6% in 2020.

Russia: Iskitimcement has announced the beginning of CEM-II ground granulated blast furnace slag (GGBFS) cement at its Iskitimcement plant in Novosibirsk Oblast. Regional Weekly News has reported that the cement will be used in road base concrete production and soil reinforcement. Iskitimcement says that the cement has high frost, abrasion and impact resistance and strength of over 5.5MPa. It will sell the cement, the seventh type produced at the plant, in 25kg, 50kg and 1t bags.

Spain: Sidenor has launched Termoslag, a software for the control of slag transit during liquid steel dumping. It aims to reduce steel’s slag content by 10%, thereby reducing raw materials and energy consumption in the steel production process and increasing slag output for circular economic uses such as cement production. Sidenor said, “We are committed to eco-innovation and the circular economy.”

US: The Slag Cement Association (SCA) has announced the recipients of its 2019 Slag Cement Project of the Year Awards. A total of 12 construction projects from across North America were chosen to showcase the broad applications of slag cement. Two research projects on slag cement use have also been recognised in the program. The winning project teams include four state Departments of Transportation (DOT), two Canadian procurement authorities, one bridge authority and the Florida Army National Guard.

“The rise in DOT and infrastructure projects we are seeing reflects the increase in demand for materials that enhance concrete’s durability, resiliency, and ultimately the value of concrete,” said SCA board president, Ed Griffith.

The event was originally scheduled to be held at the American Concrete Institute (ACI) Spring Convention in early April 2020 but was postponed due to coronavirus-related state lockdowns.
