Less carbon, same reliable performance. Stevenson Concrete’s new CarbonCure solution enables the production of the same reliable concrete but with a reduced carbon footprint. Concrete made with CarbonCure reduces CO2 by an average of 15 kilograms per cubic metre.
Fresh properties including set-time, slump, workability, pumpability, air content, temperature, and finishing are not affected; neither are hardened properties, including pH, freeze-thaw, density, colour, texture, and durability.
How it works
- CO2 produced by local oil refineries is collected, purified and transported to Stevenson Concrete where it is stored in a pressurised tank.
- A CarbonCure valve box is connected to the CO2 tank, and automatically injects a precise dosage of CO2 into the concrete during mixing.
- The CO2 reacts with the cement’s calcium ions to form Calcium Carbonate. This is embedded in the concrete, increasing its strength while eliminating the CO2.
Our extensive testing has shown that Stevenson CarbonCure is suitable for all applications including:
Commercial, Precast, Pump Mixes, Infrastructure, Residential, Landscaping
