cement and concrete recycling
The Cement Sustainability Initiative
2018-7-25 · achieved). The main source of carbon emissions in concrete is in cement production (the cement is then added to aggregates to make concrete). The cement content in concrete cannot be viably separated and reused or recycled into new cement and thus carbon reductions cannot be achieved by recycling concrete.
