CarbonBuilt & Master Builders Solutions to Grow the Market for Low Carbon Concrete Products

January 18, 2022 | News

Admixture collaboration will accelerate extension of CarbonBuilt’s proprietary low carbon concrete products from concrete masonry to precast concrete applications.

LOS ANGELES and CLEVELAND | January 18, 2022

CarbonBuilt and Master Builders Solutions® today announced a collaboration focused on the development of admixtures for use with CarbonBuilt’s low-cost and low-carbon technology platform.

These admixtures will facilitate the application of CarbonBuilt’s Reversa™ technology to a wide range of precast low carbon concrete products, including pavers, segmented retaining walls, hollow core slabs, pipes, manholes and other types of dry- and wet-cast products.

In addition, the parties will explore the use of existing and new admixture chemistries to increase carbon dioxide utilization without sacrificing product performance, product cost or process cycle time.

“While the initial application of our technology will be in concrete masonry, which was the focus of our successful DOE and XPRIZE demonstrations, we intend to expand its use to include the broader precast concrete marketplace. Admixtures can help with this, as well as with increasing our overall utilization of carbon dioxide,” said Rahul Shendure, CEO of CarbonBuilt.

“Master Builders Solutions is a recognized leader of sustainable and high performing admixture innovations for concrete, and our partnership will allow us to not only serve more markets in a more impactful way, but also to do so more quickly.”

CarbonBuilt’s formulations replace most or all of the Portland cement used in concrete products with widely available materials, reducing raw materials cost and embodied carbon simultaneously.

During the curing process, CO2 taken directly from industrial sources, biomass or emerging direct air capture solutions is permanently sequestered in the concrete.

Together, these changes result in a 10 to 30 percent reduction in raw material costs and a 60 to 100 percent reduction in carbon dioxide emissions, all while producing low carbon concrete products that meet existing specifications.

“The application of our technology to CarbonBuilt’s revolutionary process will result in high-performance precast concrete products with low embodied carbon,” said Paul Seiler, Technology Director, Master Builders Solutions.

“Having worked with their team for years, it is exciting to have this collaboration opportunity to advance the technology to its full potential.”

“Reducing carbon footprint is the defining challenge – and opportunity — in the concrete industry over the next 20 years,” said Dr. Bruce J. Christensen, Senior Vice President, Master Builders Solutions, Admixture Systems US/CA.

“We are committed to sustainable innovation in admixtures and industry partnerships to accelerate the adoption of low-carbon concrete products around the world.”
