Lafarge Canada has teamed with CarbiCrete, Quebec-based concrete binding agent and curing method developer, to process steelmaking byproduct at its St. Constant – Montreal East manufacturing cluster and extend the latter company’s market prospects. CarbiCrete technology enables the conversion of formerly sub-grade, often landfill-bound steel slag to cementitious material with binding capacity affording full portland cement replacement in certain mix designs. It also uses carbon dioxide for concrete curing, the gas mineralizing as a result of the steel slag chemistry. CarbiCrete recently commenced binder and production method commercialization through Patio Drummond, Quebec concrete masonry and hardscapes operator.

“We are committed to reducing our environmental footprint and leading the way in sustainable construction,” says Lafarge Canada (East) Vice President of Cement Andrew Stewart. “Our partnership with CarbiCrete is a testament to our dedication to offering sustainable solutions and actively participating in the circular economy.”

“Collaborating with Lafarge allows us to leverage long-established infrastructure and years of expertise in processing steel-related byproducts,” adds CarbiCrete CEO Chris Stern. “This enables us to make an immediate climate impact as we scale deployment of our technology, which reduces embodied carbon in concrete by both avoiding emissions and removing carbon through mineralization.”
