Article Synopsis
- Enhancing the ability of waste concrete to absorb carbon is essential for reaching carbon neutrality in construction, but studies so far have mainly been theoretical and overlooked the stockpiling phase.
- A new CO uptake calculation model was created to analyze how crush size, stacking methods, and environmental conditions influence carbon sequestration during stockpiling, finding that a crush size of 5-20 mm is optimal.
- Results show smaller piles improve efficiency, while higher temperatures and humidity speed up absorption; in 2021, China's waste concrete had significant sequestration potential, potentially offsetting 4% of construction-related carbon emissions.
