The new patents are: U.S. Patent 9,878,951, “Hollow-Core Articles and composite materials, methods of production and uses thereof,” issued January 30, 2018; U.S. Patent 9,938,189, “Pervious composite materials, methods of production and uses thereof,” issued April 10, 2018; and U.S. Patent 9,963,392, “Aerated composite materials, methods of production and uses thereof,” issued May 8, 2018.

“The three newly issued 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,” explained Solidia Chief Technology Officer Nicholas DeCristofaro, Ph.D. These patents can be practiced leveraging Solidia Technologies existing global patent portfolio that includes 19 issued U.S. patents, 85 issued patents outside the U.S. and over 200 outstanding patent applications around the world.

Solidia’s systems offer superior products that address the cement industry’s goal of reducing its carbon emissions, which contribute 3 to 5% of global CO2 pollution. Solidia’s patented processes start with an energy-saving, sustainable cement. Concrete made with this cement is then cured with CO2 instead of water. Together, the sustainable cement and CO2-cured concrete reduce the carbon footprint of cement and concrete by up to 70%. Additionally, up to 100% of the water used in concrete production can be recovered and recycled.

Solidia Concrete is produced using the same aggregate and mixing/forming equipment as traditional concrete, eliminating barriers to adoption. “With our increasingly comprehensive patent portfolio, Solidia ushers in the next generation of cement and concrete,” said Solidia President and 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.”
