What’s more Meta than an AI data center built using AI? #ICYMI: We partnered with @Meta and @UofIllinois to create a new AI-optimized concrete mix that is: ✅ 43% faster in early strength ✅ 35% lower carbon ✅ Similar cost Learn more: bit.ly/41prlBt 📷 Photos: @Meta

Concrete is very important to #datacenters and #AI, as it has to provide the strength and durability so that we can implement, maintain, and service AI servers. It is also a major source of #CO2 emissions.

Breaking news: @Meta and Amrize debut first-of-its-kind, AI-optimized concrete for new data center in Rosemount, MN. Using AI, we maximized concrete performance and efficiency to meet Meta’s design vision.  🔗 investors.amrize.com/news/de… #BuildYourAmbition $AMRZ

CDR = critical tool to achieving net zero. It will be awhile before we begin to tackle legacy emissions. Today’s investments will be required for getting to the gigaton-scale needed to counterbalance the truly hard to decarbonize sectors. energy.gov/articles/biden-ad…

There are many concrete opportunities to reduce #carbon emissions of our infrastructure. One of those #concrete opportunities is concrete itself. NPR story of our work at @CEEatIllinois with @lrvarshney @ECEILLINOIS, @uofigrainger and @Ozinga @Meta npr.org/2022/05/18/109968062…
Can a new concrete mixture help reduce the construction industry's carbon footprint?

Can a new concrete mixture help reduce the construction industry's carbon footprint?

A data center in DeKalb, Illinois, is the testing ground for a new sustainable concrete. Is this greenwashing or can new mixtures contribute to reducing the construction industry's carbon footprint?

Yes, we'll soon be reporting our full deployment results demonstrating contractors can use our formulations in their standard process, and it does indeed halve embodied carbon from other formulations and is just as strong #AI4G @prof_garg_ @JuliusKusuma sustainability.fb.com/wp-con…
