Hi CLF Community!
Reaching out on behalf of SEAOSC for a project where the Sustainable Design and Concrete Committees are teaming up to collect and share best practices to help engineers initiate the conversation around low-carbon concrete.
- Have you had a conversation with a client, contractor, or concrete supplier about using low-carbon concrete on a project?
- When is the right time to start talking about low-carbon concrete? How can you initiate? Letter? Specifications?
- As a contractor / supplier, when do you need to be making decisions about mix design? And impacts like data availability or testing protocol for 56-day specified strength? Others?
- What issues have come up that have inhibited adoption of lower CO2e mixes? Curing time? SCM availability? Others?
If anyone has any examples (letters, specification language, etc.) or lessons they are willing to share, it would be much appreciated! We’re hoping to get feedback from across AEC!
