PISCATAWAY,
N.J.--(BUSINESS
WIRE)--The U.S. Patent and Trademark Office issued
a patent for the structure of CO2-cured Solidia Concrete™, advancing the
performance and sustainability of materials available to the global
construction and materials industries. Solidia Technologies® holds the
exclusive licensing rights to the patent, which is held by Rutgers University,
where the original generation of the material was invented.
U.S. Patent No. 9,868,667,
"Bonding Element, Bonding Matrix and Composite Material Having
the Bonding Element and Method of Manufacturing Thereof," covers
the composition of matter of the non-hydraulic concrete.
“The hydrate
bonds in conventional concrete can compromise that material’s strength and
durability,” explained Solidia Chief Technology Officer Nicholas DeCristofaro,
Ph.D. “With CO2-cured concrete, bonding elements based on silica and calcium
carbonate create a wide range of attractive properties, including mechanical
strength, resistance to freeze-thaw deterioration, and resistance to sulfate
attack.”
Solidia
addresses the cement industry’s goal of reducing its carbon emissions, which
contribute 3-5% of global CO2 pollution. Solidia’s processes start with an
energy-saving, sustainable cement, then cure concrete with CO2, reduce the
carbon footprint of cement and concrete up to 70%, and recycle 60 to 80% of the
water used in production. Using the same raw materials and existing equipment
as traditional concretes, the resulting products are higher performing, cost
less to produce, and cure in less than 24 hours.
“Our
next-generation concrete offers a competitive edge to the global US$1
trillion concrete and
US$300 billion cement markets,
advancing profitability and sustainability in an industry that needs both,”
said Solidia President and CEO Tom Schuler.
Currently in
commercialization for large- and small-scale applications, the initial
technology focus was on unreinforced precast applications, including pavers and
blocks. Solidia is now developing processes for reinforced applications,
including aerated concrete, railroad ties, architectural panels and hollow core
extrusions.
Solidia’s patent
estate includes over 200 patent applications worldwide, with 32 issued and 14
scheduled. Investors include Kleiner Perkins Caufield &
Byers, Bright Capital, BASF, BP, LafargeHolcim, Total Energy Ventures, Air Liquide, OGCI Climate Investments, Bill Joy and
other private investors.
