New MIT Research Reveals How CO₂ Mineralization Improves Concrete Microstructure
First-of-its-kind research from the Massachusetts Institute of Technology’s Masic Lab and CarbonCure Technologies provides the most advanced explanation yet for how CO₂ mineralization supports cement efficiency in concrete while maintaining performance, building on what CarbonCure concrete producers have already applied across more than 20,000 mix designs and 11 million truckloads worldwide.
The new peer-reviewed study in the Journal of the American Ceramic Society provides molecular-level evidence, using MIT's in situ Raman microspectroscopy to observe CO₂-activated cement hydration unfold in real time:
- Injected CO₂ triggers a three-stage hydration sequence.
- This improves early-age microstructure, resulting in a more evenly distributed, interconnected binder.
- Calcium carbonate particles are permanently sequestered within the concrete matrix.
"The research findings provide the strongest experimental validation yet of carbon mineralization in concrete, explaining how carbon utilization technologies help producers reduce cement content and costs while delivering consistent, high-performing concrete."
