CO2 Concrete

Researchers Vivian Tam (School of Built Environment) (opens in a new window) and Khoa Le (School of Engineering) (opens in a new window) have developed a recycled concrete product which is enhanced through pressurised carbon dioxide (CO₂).

This material has been used to make biosecurity structures for the Hawkesbury Farm (e.g. structures for cleaning boots) associated with visitors coming onto the site.

The CO₂ concrete has also been used on more structural features such as concrete pads under and around stock water troughs. These applications are continuously monitored to assess durability.
