Abstract Scalable and sustainable construction materials are essential for decarbonizing the built environment and advancing the circular economy. Here, we present a robust, water-based method for producing defect-free, few-layer graphene via high-shear exfoliation of graphite, using a surface energy-matched solvent and a polycarboxylate stabilizer. Operating at ~8.4×104 s⁻1, the process yields stable graphene dispersions (up to 5 g L⁻¹) compatible with cementitious systems.

Robin Kutesa, CC BY Australia is getting hotter. Climate change is driving more frequent and prolonged extreme heatwaves and our homes are struggling to keep up. Alarmingly, many Australian houses – especially older ones – weren’t designed for these harsh conditions. During a heatwave, large parts of the country’s interior can soar above 40°C. That’s not only uncomfortable but also dangerous, as extreme heat puts residents at serious health risk.
