Three recently issued U.S. Patent and Trademark Office patents cover processes and products based on Solidia Technologies’ cement and carbon-curing materials and methods. The U.S. Patents are designated 9,878,951, “Hollow-Core Articles and composite materials, methods of production and uses thereof;” 9,938,189, “Pervious composite materials, methods of production and uses thereof;” and, 9,963,392, “Aerated composite materials, methods of production and uses thereof.”

“The[se] patents teach examples of enhanced utility in Solidia Concrete applications, such as improved durability, reduced manufacturing cost, and fast curing within 24 hours compared to 28 days for conventional concrete,” says Solidia Chief Technology Officer Nicholas DeCristofaro, Ph.D. They can be practiced leveraging the company’s existing global intellectual property portfolio, he adds, which spans 19 issued U.S. patents, 85 issued patents outside the U.S., and 200-plus outstanding patent applications around the world.

Solidia Technologies advances the cement industry’s goal of reducing carbon dioxide emissions, starting with an energy-saving, sustainable binder. Concrete bearing the material is then cured with carbon dioxide instead of water. Together, Solidia cement and CO2-cured concrete reduce the carbon footprint by up to 70 percent when compared to conventional slab or structure mix design and finishing methods. Additionally, up to 100 percent of the water used in production can be recovered and recycled. Solidia Concrete bears the same aggregate and mixing/forming equipment as conventional material, eliminating barriers to adoption. 

“With our increasingly comprehensive patent portfolio, Solidia ushers in the next generation of cement and concrete,” affirms CEO Tom Schuler. “Our technologies are helping make sustainability business as usual in the global US$1 trillion concrete and US$300 billion cement markets.”
