Holcim has successfully placed its first 99.2% clinker-free concrete pavement in North America, marking a significant milestone in its commitment to sustainable building. This innovative project, completed in collaboration with Stoneway Concrete, resulted in a 74.7% reduction in CO2 emissions compared to standard concrete using Type IL cement.
“Our net-zero goals are ambitious, and to get there, we need to continuously push the boundaries to decarbonize building at scale,” said Toufic Tabbara, Holcim regional head, North America. “Through cutting-edge research and development, our team of engineers has created a virtually clinker-free cement. This innovation represents a substantial reduction in carbon emissions and a major step in sustainable building.”
The 30m3 slab-on-grade concrete pad, engineered to withstand heavy truck traffic, was poured at Holcim’s Seattle plant in May 2024. Holcim’s approach in this project substituted clinker, traditionally the primary component in cement production, with a slag activator, significantly decreasing the energy required and resulting in a much lower carbon footprint.
Cory Cannon, vice president of Cement Sales and Logistics, stated, “As a leader in our industry, we believe in setting the standard for product innovation and sustainability. This product exemplifies our ability to swiftly introduce eco-friendly building solutions, and we’re pleased with the positive reception from our customers, showing the industry’s readiness to embrace these advancements.”
This demonstration sets the stage for further collaboration with customers in the Pacific Northwest, with early commercial pours anticipated in June and July of 2024. As a global leader in sustainable building solutions, Holcim remains at the forefront of decarbonizing construction with cutting-edge, low-carbon, and circular solutions.
Holcim’s success in this project underscores its ability to develop high-quality solutions that significantly accelerate decarbonization without compromising performance. This achievement is a testament to Holcim’s ongoing commitment to sustainability and innovation in the construction industry.
