The Slag Cement Association (SCA) participated in the paving of test sections at MnROAD – Minnesota’s Cold Weather Pavement Testing Facility, showcasing innovative carbon content reduction strategies.
SCA members provided slag cement and other materials for several innovative mixes. The SCA-sponsored test section included a quintenary mix (five ingredients) and materials provided by Holcim.
The mix included portland-limestone cement, slag cement, fly ash, natural pozzolan, and a reduction in total cementitious materials, achieving a final composition that features less than 50% clinker content. SCA said this mix dramatically reduces the carbon footprint associated with concrete construction, offering a more sustainable yet durable solution for roadway infrastructure.
“SCA and its members are dedicated to reducing the embodied carbon associated with cement production and advancing the use slag cement in infrastructure projects across North America,” said Nick Brimley, marketing director of SCA. “Holcim’s innovative mix exemplifies our industry’s commitment to advancing sustainable construction materials.”
Located near Albertville, Minn., MnROAD works in conjunction with MnDOT’s Materials & Road Research Lab. MnROAD has over 50 unique test sections on several roadway segments.
