And why CO2 mineralised concrete is promising
Concrete is the most used substance on the planet, second only to water. The simple act of choosing low carbon concrete over traditional concrete can greatly reduce the total carbon footprints of all new buildings. Indeed, low carbon concrete has become an increasingly powerful way for the built environment sector to seriously tackle global carbon emissions.
To be sure, low carbon concrete containing recycled components has been in use in Asia since the 2000s. We have seen quite an array of concrete mixes with varying amounts of such secondary materials. Recyclables such as fly ash, calcine clays, ground granulated blast-furnace slag are not uncommon in low carbon concrete mixes in Asia today.
