From Carbon to Simply Better Concrete
CarbonCure manufactures a technology for concrete producers that introduces recycled CO2 into fresh concrete.
In a process known as CO2 mineralization, the CO2 is converted to a mineral and becomes permanently captured. This enables production efficiences as well as carbon footprint reductions.
Everyone wins when carbon becomes concrete
Ready mix and masonry concrete producers benefit from improved operations.
Architects, engineers, builders and building owners can reduce the carbon footprint of building and infrastructure projects without making compromises.
Policy makers can take immediate action to reduce the carbon footprint of the built environment with a business-friendly solution.
Solutions
Ready-mix
Did you know that 50% of the construction industry has gone green?
But with rising material costs, tough competition from other building products, labour shortages and strict construction deadlines, what if you can’t afford to go green?
CarbonCure helps ready mix concrete producers improve their operations while growing their business with the green building market.
Improve your operations without incurring capital costs
Injecting CO₂ into concrete improves the compressive strength, enabling you to adjust the cementitious content in your mix designs. The CarbonCure Technology has no upfront capital costs, allowing you to quickly see a positive return on your investment.
Make better concrete, simply
The CarbonCure Technology is seamlessly integrated into your plant’s existing batching system and has no impact on daily operations or on cycle time. Aside from improving compressive strength, there is no impact on the concrete’s fresh or hardened properties.
Specifiers
Did you know that concrete is the most abundant man-made material in the world?
The production of cement, the critical ingredient that gives concrete its strength, is responsible for up to 7% of the world’s total CO₂ emissions.
Concrete as a % of all Building Materials:
Concrete has a smaller CO₂ impact per volume than other materials, but its abundance means that it creates more CO₂ overall than any other material.
Have your cake and eat it too
Designers can capitalize on the unique qualities of concrete they rely on: strength, versatility, durability, sound-reduction and thermal-insulation - with a reduced carbon footprint.
Carbon footprint reduction of ready mix: Approx. 25 pounds CO₂ per cubic yard (sequestered + avoided CO₂)
Carbon footprint reduction of masonry: Approx. 1 pound CO₂ per 30 standard blocks (sequestered)
It’s as easy as flipping a switch
The use of the CarbonCure Technology has no impact on the fresh or hardened properties of ready mix or concrete masonry, including durability, finishing, workability, pump-ability, temperature, pH or appearance.
Technology
Recycling CO2 to make simply better concrete.
The CarbonCure Technology injects a precise dosage of carbon dioxide (CO2) into ready mix concrete and concrete masonry products, where the the CO2 becomes chemically converted into a mineral.
Advantages and Applications
Ready Mix
The CarbonCure Technology improves the compressive strength of ready mix concrete, which enables concrete producers to optimize their mix designs, while reducing the carbon footprint of their concrete.
Masonry
The CarbonCure Technology reduces the carbon footprint of concrete masonry, which enables masonry producers to differentiate their CMU brand and increase sales with the growing green building market.
Effectiveness of CO2 as a cement replacement in ready mix concrete
CO2 Source
The CarbonCure Technology uses CO2 sourced from industrial emitters. Established gas suppliers collect, purify and distribute the CO2. The CO2 is stored at concrete plants in pressurized vessels that are refilled regularly by the gas suppliers.
The Equipment
The patented CarbonCure Technology is retrofitted into existing concrete plants in a single day. Batching is controlled by a simple interface integrated with the batch computer. In a ready mix dry batch application, the CO2 is injected into the hopper; while in a central mix or masonry application, the CO2 is injected into the central mixer.
Chemistry
Once injected into the wet concrete mix, the CO2 reacts with calcium ions from cement to form a nano-sized calcium carbonate mineral that becomes permanently embedded in the concrete.
Effects on Concrete
The CarbonCure Technology has no effect on fresh properties, including set-time, slump, workability, pumpability, air content, temperature, and finishing; nor on hardened properties including pH, freeze-thaw, density, colour, texture, and durability.
Sustainability Advantage
CO2 collected from emitters has many applications, including carbonated beverages. In almost all other applications, the CO2 eventually makes its way back into the atmosphere. With the CarbonCure Technology, the CO2 is chemically transformed into a mineral, which means it will never be released into the atmosphere as a greenhouse gas.
