Australia: Boral has launched new binary- and triple-blend concrete mixes incorporating calcined clay as a supplementary cementitious material (SCM). The mixes offer comparable workability to ‘traditional’ reduced-CO₂ concrete. The launch builds on collaborations with SmartCrete, technology developer Calix and the University of Technology Sydney between 2020 and 2024.
Separately, Quarry Magazine has reported that Boral has also completed demonstrations at scale to show that crushed recycled concrete can absorb captured CO₂. The producer has developed novel concrete mixes using the resulting recycled recarbonated aggregates.
