US: Heidelberg Materials North America and Levy Group of Companies signed a granulated blast furnace slag (GBFS) supply contract on 9 August 2023. Under the contract, Levy Group of Companies will supply Heidelberg Materials North America with 400,000t/yr of GBFS for use in its slag cement production. Deliveries will begin in early 2024. Heidelberg Materials North America says that it has upgraded its Speed cement plant in Indiana to increase the efficiency with which it grinds GBFS. Following the inauguration of its nearby 2.4Mt/yr Mitchell cement plant in June 2023, Heidelberg Materials North America plans to transition the 1Mt/yr to 100% speciality and slag cement production. Levy Group of Companies will supply the GBFS from steel industry sites in the Midwest Region.

Heidelberg Materials Midwest US president Axel Conrads said “Our agreement with the Levy Group of Companies to secure a consistent supply of slag granules will help us accelerate the transition of the Speed plant to slag cement production and better meet the increasing demand for more sustainable cement products in the growing Midwest market.”
