Heidelberg Materials converts Indiana cement plant to a slag grinding facility

SPEED, Indiana — Heidelberg Materials has successful converted its cement plant in Speed, Indiana, to a slag grinding facility.

The company states this will allow the plant to better support the increased demand for sustainable products in the Midwest American market.

Following last year’s opening of its new state-of-the-art cement plant in Mitchell, Indiana, Heidelberg Materials ceased portland cement production at its manufacturing site in Speed, and focused on modifying the facility to produce slag cement from domestically-sourced slag granules.

Heidelberg Materials states that replacing a portion of conventional portland cement with slag cement in a concrete mix significantly lowers its environmental impact. The Speed site has an annual grinding capacity of more than 400,000 tonnes. It also serves as a distribution hub for cement produced at the Mitchell plant as well as a broad range of specialty cementitious products.

Heidelberg Materials explains these adjustments reflect the company’s commitment to achieving net-zero emissions in North America. Recently, Heidelberg Materials was selected for funding of up to US$500 million by the US Department of Energy to advance industrial-scale carbon capture, transport and storage at its Mitchell cement plant. At the Edmonton cement plant in Alberta, Heidelberg Materials is currently developing the world’s first full-scale carbon capture, utilisation, and storage solution in the cement industry.
