The company's cement-free building materials are
revolutionizing sustainable construction, even in the heart of
New York City.
SAN
LEANDRO, Calif., Sept. 30,
2024 /PRNewswire/ -- C-Crete Technologies, a pioneer
in sustainable building materials, has achieved a groundbreaking
milestone by pouring the world's first granite-based concrete
completely devoid of Portland
cement and CO2 emissions.
C-Crete's
granite-based concrete is a key progress in reducing the heavy
carbon footprint of limestone-based concrete
The granite concrete was poured July
8 at 270 Park Avenue, Manhattan, the site of JPMorganChase's new
global headquarters, designed by the renowned architectural firm
Foster + Partners and engineered by Severud Associates Consulting
Engineers.
The pour was for a 12 cubic yard slab of granite
concrete for a topping slab located on the upper lobby of the
supertall. (A supertall is a skyscraper between roughly 1,000 and
2,000 feet tall.) The pour builds upon previous successful pours of
C-Crete concretes at other buildings, each employing a distinct
feedstock, such as zeolite or basalt.
Granite is a non-carbonate rock primarily composed of silicon,
aluminum and calcium, three of the Earth's most abundant elements.
In terms of volume, it is the most abundant rock on Earth, even
more plentiful than the limestone used for
manufacturing Portland cement.
And, unlike Portland cement –
the production of which is responsible for approximately 8 percent
of global CO2 emissions – cement binders made from granite, zeolite
and basalt emit no CO2 during manufacturing.
C-Crete's granite-based
concrete maintains similar or even better performance than
Portland cement. It shows a
compressive strength exceeding 5,000 psi. It demonstrates
pumpability, workability, setting time and surface finish akin to
conventional concrete, while meeting ASTM International standards
for mechanical and durability properties, a fact verified by
independent third parties. Crucially, it achieves these feats while
maintaining cost-parity with conventional concrete.
Thus, C-Crete's granite-based concrete is helping the
construction industry take a significant step forward in reducing
its environmental footprint following the 200-year reign of
carbon-heavy limestone-based concrete as the backbone of our
buildings, schools, hospitals, and other built infrastructures.
C-Crete Technologies is a leading materials science company
committed to inventing, building and scaling up the next generation
of infrastructure materials with ultra-low or negative CO2
footprints. With a relentless focus on environmental stewardship
and technological innovation, C-Crete aims to address the global
challenges of climate change while delivering superior
infrastructure materials at scale.
