The Process

The steps in CarbiCrete’s process are identical to those of conventional concrete making, with a few key differences.

With cement-based concrete, the first step involves mixing cement with aggregate and water. With CarbiCrete, cement is completely replaced with otherwise landfilled steel slag, which is mixed with the other materials using standard equipment.

The mix is then formed into masonry products using conventional machinery.

In order to cure the concrete, it must be placed into a specialized curing chamber into which CO2 is injected. Within 24 hours, the concrete has reached full-strength.

Life Cycle Assessment

CarbiCrete’s net carbon-negative impact has been validated by a third-party life cycle assessment. It starts with a 100% reduction of  carbon dioxide emissions associated with cement production. Any manufacturing emissions are more than offset by the permanent sequestration of carbon dioxide that otherwise would have been released into the atmosphere, but is instead mineralized in the product during curing. Even when additional transportation and conversion impacts are considered, CarbiCrete’s full LCA results in net carbon-negative environmental impact.
