Hi all,
Here's a good follow up to Maria's steel question on Monday. We have a Midwest project that unfortunately (from a carbon perspective) is required to use a traditional, thick precast facade. We’re working with the contractor and potential future (not yet bid out) fabricators to determine an appropriate % of pozzolanic material replacement that will allow for visual consistency, and are seeking wisdom from other teams that have been through this. What is the tipping point, beyond which the % of flyash is a problem? What are the other factors that contribute to success/problems?
We are looking for:
- Example projects in the US
- What percentages were successfully used
- How old is the project
- What issues were encountered, if any
I imagine that others here would have already been through this exercise. Any thoughts? We are also reaching out to other construction partners and the Precast Institute. Nadav, can you also forward this to the construction group?
We are also looking to include part lightweight concrete for the nonstructural sections and local materials. Are there any other carbon reduction strategies have have implemented successfully?
Thanks,
Mara
