Rutgers, Solidia Technologies Receive Two New Patents Describing Sustainable Concrete Products

The U.S. Patents Office awarded two new patents to Rutgers, The State University of New Jersey, that describe sustainable concrete products that cure and harden by consuming carbon dioxide (CO2) instead of water.1,2 The commercialization of the products is occurring under an exclusive licensing agreement with Solidia Technologies®, a New Jersey-based start-up developing sustainable building materials that can reduce the carbon footprint of concrete products up to 70 percent.

Solidia Concrete™ is manufactured using identical mixing and forming processes as those used to produce concrete made with ordinary Portland cement (OPC). It is then cured and hardened by a previously patented chemical reaction between Solidia Cement™ and gaseous CO2.3,4 This unique aspect of Solidia Concrete curing allows precise control of the curing process, permits the incorporation of a broad range of sands, aggregates, and reinforcements, reduces water consumption up to 80 percent, and enables manufacturers to operate at higher speeds while minimizing material waste. Solidia Concrete cures in less than 24 hours as compared to the 28 days required for OPC-based concrete to achieve full hardness.5

When the reduced CO2 emissions associated with Solidia Cement production are combined with the CO2 reacted into Solidia Concrete, the carbon footprint of concrete products can be reduced by up to 70 percent.

Suitable for large- and small-scale applications, Solidia Concrete parts can be designed for compressive strength, abrasion resistance, efflorescence, and freeze-thaw cycling resilience that are equal to, or better than, that of conventional concrete.

“Solidia Concrete can be adapted easily by manufacturers of conventional concretes, fitting into the industry’s existing infrastructure and raw materials supply chains anywhere in the world,” said Solidia Chief Technology Officer Nicholas DeCristofaro, Ph.D. “Products made with Solidia Concrete are more stable, more durable, and more cost-effective than traditional concretes, offering the global construction and building materials industries a path to greater sustainability and profitability.”

Solidia’s licensing agreement with Rutgers covers a portfolio of more than 50 U.S. and foreign patents and patent applications for technologies originally co-invented by Richard (Rik) Riman, Ph.D., Rutgers distinguished professor of materials science and engineering and Solidia Founder and Board member, and Vahit Atakan, Ph.D., Solidia’s R&D director and former Rutgers graduate student and research associate.
