Data Center Ductbank Implementation

Location: Aurora, Colorado

Prometheus Materials successfully completed a ductbank installation using ProZERO™ for a major data center project. Approximately 63 tons of ProZERO™ were used at an 8% cement replacement level, supporting the placement of over 2,500 cubic yards of low-voltage ductbank.
Material was delivered via bulkers and stored onsite in temporary silos before being incorporated into concrete trucks using standard batching and handling practices, demonstrating compatibility with conventional ready-mix operations.

Answers to our most frequently asked questions

Where do you grow the algae?

We have strategic partners that are based in key growing climates to ensure efficiencies and effectiveness of the algae

What’s the dosage of ProZERO™ needed for a typical mix?

Dosage is based on project goals and mix specifications. For ready-mix producers, this is typically set by targeted cement replacement levels (10–40%). We work with suppliers to determine the appropriate replacement percentage needed to meet targeted GWP and carbon reduction goals within your local market and your project.

Who does the testing prior to a pour?

We recommend that you or your lab conduct testing using your own materials and placement practices. We provide mix guidance and technical support throughout the process.

What do ready-mix suppliers need to do to integrate your product into our mixes?

ProZERO™ integrates similarly to other OPC replacements (slag, natural pozzolan, fly ash, limestone, etc.). Suppliers can use existing handling and batching practices. We work with suppliers to determine the best delivery method. ProZERO™ has been delivered to partners, job sites, and batch plants via bags, super sacks, and bulker trailers.

Shipping

We expect this application to be viable, though it has not yet been formally tested. A trial batch is recommended prior to deployment.

How much does it cost?

It comes in a bulk powder, delivered in a short ton. It can be shipped in a Super Sack on trailer, or dry powder in a bulker.

Shipping is at the cost of the buyer, FOB, Longmont CO.
