Amrize, a Chicago-based provider of construction materials, supplied materials to the 100,000-square-foot Theodore Roosevelt Presidential Library in Medora, North Dakota.
Amrize says the building was designed to meet the requirements of the Living Building Challenge 4.0 while withstanding the climate of the Badlands.
Living Buildings are regenerative buildings that connect occupants to light, air, food, nature and community; self-sufficient and remain within the resource limits of their site and create a positive impact on the human and natural systems that interact with them, according to its website.
Amrize supplied 5,000 short tons of American-made, low-carbon cement produced at its flagship plant in Ste. Genevieve, Missouri, and 4,000 short tons of slag from Chicago for the project.
Amrize worked with Dickinson Ready-Mix, a Dickinson, North Dakota-based ready mix concrete supplier, to develop a custom ternary blend of Type 1L cement (Portland-Limestone cement), slag and fly ash. The blend needed to deliver the durability required for North Dakota’s demanding environment while helping reduce embodied carbon.
Amrize collaborated with Dickinson Ready-Mix to develop and refine seven project-specific concrete mix designs, achieving supplementary cementitious material (SCM) replacement rates of 50–70 percent while meeting strict performance requirements for strength, durability and constructability.
“Projects like the Theodore Roosevelt Presidential Library demonstrate that American-made low-carbon building solutions can meet some of the industry’s toughest performance requirements without compromising durability,” says Patrick Cleary, senior vice president of U.S. cement and supply chain at Amrize. “By working closely with our partners from the outset, we were able to optimize the mix designs and provide the technical support needed to help achieve the project’s ambitious performance and low-carbon goals.”
