The Concrete supplier utilized multiple "mixes" of concrete in the project. A mix has slightly different functions, which I think would mean it is a separate product based on the USGBC definition. Although they only provide one EPD that covers the multiple mix types. Would each concrete mix on the project count as a separate product, meaning we could apply that EPD to each?

I don't think each "concrete mix" would count as a separate product, but the concrete admixtures would be considered separate products since each component (admixture, aggregate, and cement) serve a different function.

Each mix is a different product. Think of the paint example. Different colors of the same type of paint do not count, but different paints of the same color are different products and do count. Concrete is all the same color, but each mix has a different composition and function/purpose. Therefore yes, each mix can be counted as an individual product. The one caveat would be that different slumps of the same mix would not be different products. This would equate to using different colors of the same paint.

I agree that different mixes can typically be counted as separate products, assuming they're being used for different applications and are designed for different strengths and psi ratings. The NRMCA industry-wide EPD covers numerous mix designs (https://www.nrmca.org/sustainability/EPDProgram/Downloads/EPD10080.pdf). If you haven't already, confirm that the concrete supplier working on your project is listed as a participating manufacturer on the EPD, in order to count those products.

Hi guys,
may I follow up on this since there are still some unclarities on my side. If I have a mixture of floor coatings, where each component of said mixture has its own EPD. Does this even count as one product? Or does it even count for multiple products? I am really uncertain.

As said by Craig and Leanne, if the mixture of floor coatings have a different composition and/or serve different purpose/function, then we can count as multiple products.

Hello, I'm a little confused about how to report Concrete Mix Design on the LEED coversheet.
I just received the LEED product data reporting form from the subcontractor, and they basically listed each Mix design; A, B, C, D, with each corresponding cost. That's it.
I returned the coversheet to them because none of the Admix products from the submittal were listed, along with corresponding information and declarations.
I do have the admix test reports with the products / product data sheets.
Please correct me if I'm wrong but shouldn't each of the materials for each mix on the test report be listed? And do I need the individual cost of each material in each mix or is the bulk price ok? Please guide me and Thank you! - AP

Hi Allison, there are several approaches depending on the contributions you want to report. My suggestion is to request the EPD for each concrete mix. They may not be available where you are, but asking the manufacturer can encourage them to generate EPDs. Many projects find they can achieve the EPD threshold with other materials, e.g., materials in partition assemblies, floor, wall, ceiling finishes, etc.

Thank you for your response Kai. Very helpful.
