The innovative cement-free ready-mix concrete is essentially CO2-free and actually absorbs CO2 over time, helping propel the construction industry towards net-zero emissions

SAN LEANDRO, California, July 18, 2023 /PRNewswire/ -- C-Crete Technologies proudly unveiled its innovative cement-free concrete, a first-of-its-kind innovation in the construction industry, with its commercial building debut in Seattle . The sustainable alternative to Portland cement produces almost no carbon dioxide in its manufacture and actually absorbs CO2 from the air over time.

Portland cement is responsible for around 7% of total CO2 emissions worldwide. If used instead, the new material can help substantially reduce the environmental impact of the construction industry. Each ton of C-Crete binder that replaces Portland cement prevents approximately 1 ton of CO2 emissions. In addition, the product uses a set of natural minerals and industrial by-products, which guarantees an abundant raw material.

Approximately 60 tons of cement-free concrete was poured into the foundation and shear walls of the Seattle project at 7,200 Woodlawn, an adaptive reuse development of a historic 120-year-old brick building that used concrete as part of a seismic retrofit.

The concrete was highly fluid, pumpable, and achieved a bearing strength of over 5,000 pounds per square inch, exceeding the ASTM standard of approximately 4,000 psi for most residential, commercial, and infrastructure concrete applications. It also meets other key industry standards, exhibits exceptional durability such as resistance to freeze-thaw cycles, alkali-silica reactions, and chloride and acid penetrations, and is compatible with conventional concrete mixes, allowing for easy integration into existing construction practices.

"We are delighted to introduce our cement-free concrete, a game changer in sustainable construction," said C-Crete founder and CEO Rouzbeh Savary, PhD. "Our binder is a direct replacement for Portland cement that dramatically reduces carbon emissions. Since our product meets industry standards and is cost parity with conventional concrete, it opens up a whole new era in construction."

C-Crete used Heidelberg Materials, a global ready-mix concrete and building materials company, to deliver the cement-free concrete for this project.

Donald Davies is a Seattle building owner and president of Building Transparency, a nonprofit organization dedicated to enabling the construction industry to address the role of embodied carbon in climate change. "As a 33-year-old developer, structural engineer and leader in low carbon construction, I see a lot of low carbon concrete being discussed," Davies said. "I see exciting developments, but few are ready to scale production the way C-Crete can now. Cement-free, low-carbon concrete isn't just a pipe dream. It's real, it is now, and it works. This project shows that it is possible, today."

With the successful application of its concrete in Seattle, C-Crete is now poised to transform the construction landscape across the country and beyond. The company looks forward to collaborating with architects, designers, general contractors, ready-mix concrete companies, building owners, and decision makers for infrastructure projects to accelerate adoption of its sustainable concrete.

About C-Crete Technologies: C-Crete Technologies is a leading materials science company committed to inventing, building and scaling the next generation of ultra-low or negative CO2 footprint infrastructure materials. With a relentless focus on environmental stewardship and technological innovation, C-Crete aims to address the global challenges of climate change while offering scalable materials for everyday use.
