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.
