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.

Taiheiyo Cement, JFE Steel and the Global Institute for Environmental Technology researching producing carbonates from steel slag
Written by Global Slag staff
15 May 2020
Japan: Taiheiyo Cement, JFE Steel and the Global Institute for Environmental Technology are working together to develop a carbon capture and storage system. The system will use wet alkaline earth metals extracted from steel slag to produce carbonates from exhaust gases at cement and steel plants. The partners are investigating the possibility of using these carbonates, specifically calcium carbonate and magnesium carbonate, as additives in cement production at Taiheiyo Cement’s plants. Taiheiyo Cement president Masafumi Shigehara said, “With the effects of climate change becoming apparent both in Japan and overseas, the importance of global warming counter-measures is increasing.”
