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
“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
Schuler. “Our technologies are helping make sustainability business
as usual in the global US$1 trillion concrete
and US$300 billion cement
