Cement production accounts for 8% of the world’s GHG emissions. As the green building market continues to grow, concrete users are looking for reliable materials that reduce cement use. When compared cement-based CMUs, CarbiCrete CMUs exhibit equivalent or better mechanical and durability properties. They have the same water absorption properties, but higher compressive strength by up to 30% and display better freeze/thaw resistance. CarbiCrete concrete offers the same or better quality and performance that users expect, but with a carbon-negative footprint.
Validating CarbiCrete’s net carbon negative impact involves performing an industry standard Lifecycle Analysis (LCA). Our third-party LCA methodology starts with a 100% reduction of the carbon dioxide emissions from eliminating cement use in concrete. It drives net negative emissions with the permanent sequestration of carbon dioxide that is mineralized in the product curing. Even when additional transportation and conversion impacts are considered, CarbiCrete’s full LCA results in net carbon-negative concrete products.
CarbiCrete works with local concrete manufacturers to produce cement-free CMUs for commercial, residential, and landscaping use. Using steel slag instead of cement makes CarbiCrete an ethical and affordable solution for your project. Incorporating CarbiCrete CMUs can help a project achieve LEED certification or meet other sustainability criteria. Our blocks are currently being produced at Patio Drummond in Quebec, with plans underway to expand production into new markets.
Carbon Benefit Accounting and Verification
Achieving full accounting for the carbon benefits from using the CarbiCrete process requires monitoring the output and reporting those to the validation agencies. CarbiCrete’s process management information system helps to do this in partnership with the customer. Providing all of the necessary detail and support ensures that both abatement and removal benefits are fully counted and provide confidence to those who use those benefits in their own carbon accounting.
