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
The carbon reduction potential of CarbiCrete’s technology starts with the elimination of carbon dioxide emissions associated with cement production. CarbiCrete’s incorporation of carbon dioxide removal (CDR) technology through carbon mineralization curing further lowers the global warming potential (GWP) of CarbiCrete products. Through quantifying our supply chain data for A1 (material), A2 (transport) and A3 (manufacturing), our EPD demonstrates CarbiCrete’s potential to significantly reduce concrete’s embodied carbon emissions.
Environmental Product Declaration
CarbiCrete’s cradle-to-gate facility-specific EPD for concrete masonry units (CMUs) produced at Patio Drummond is verified by ASTM under Concrete Masonry and Segmental Concrete Paving Product EPD Requirements, November 11 2020. V1 .0. Developed by Climate Earth, the leading EPD provider in the concrete industry, this EPD quantifies our CMUs’ global warming potential (GWP) at 11.7 kg CO2 eq. per m3, a value 20 times lower than the industry average and a significant improvement compared to other low-carbon products on the market.
