All,

Our firm has been struggling to find carbon reduction strategies for concrete that move us beyond a fly ash only approach. Frankly, the knowledge just isn't there internally or with our consultants. We've known that there are a few folks out there that have a deep bag of tricks, but we haven't had the chance to work with them directly. Fortunately we've been able to convince one of them, Dirk Kestner with Walter P. Moore, to join us for a webinar on advanced strategies for concrete carbon reduction. The webinar is going to be great and we actually have a number of the structural engineers on our own projects registered.

The registration link is below and feel free to share, there is no good reason to keep this knowledge within a limited group!

Thanks for sharing Rodrick! This is one of the many pots I’m trying to stir as well. It is hard keep leaderships attention on a subject when you have no solution. No bag of trick here, but I would love to partake in the hunt.

While not a cement replacement, Portland Limestone Cement (type 1L, PLC) has a lower embodied emissions footprint and can take the place of normal type I cement. Optimizing mix strength and strength achievement duration is another intermediate step to carbon reduction. Of course there's companies like Carbon Cure or Solidia (https://www.solidiatech.com/solutions.html) who are capturing carbon and injecting into mixes. But agreed....not a lot of emerging innovations I'm aware of for cement replacement.

Mark - This is a great point and a strategy that is agnostic to location. Outside of a few markets, the availability of the novel cement replacements definitely drops off.

This is great, and I'm so sad I'm booked at that time! Any chance you're recording it + posting it for later (please please please)?

Roderick, One "emerging product" I've heard of is Limestone Calcined Clay Cement (LC3): https://www.lc3.ch/

The emerging SCM that I'm most excited about is glass pozzolan. It takes an abundant and underutilized resource, recycled glass, and turns it into a cleaner Portland cement replacement. And, for Christmas 2019, glass pozzolan got its own ASTM standard. Learn more here: https://www.buildingproductecosystems.org/glass-in-concrete
