Mexico: Cemex says that it is involved in a working group “focussed on the application of FastCarb aggregates to concrete production” as part of its efforts towards net-zero CO2 concrete production. FastCarb, administrated by the US-based International Research and Exchanges Board, is a project aimed at the production of aggregates from recycled concrete containing trapped carbon dioxide (CO2) requisitioned from industrial exhaust streams.
Cemex said, “After completing the first phase of the experimental approach at the laboratory level with promising preliminary results, the project is now entering the second phase seeking to tackle the industrial approach. In this industrial approach phase, Cemex was recently assigned to evaluate the physical and mechanical properties of the carbonated recycled concrete aggregates when used in ready-mix concrete in the laboratory facilities at the Cemex France National Technical Centre.”
