San Leandro, California – September 30, 2024:
In a significant stride towards sustainable construction, C-Crete Technologies has successfully poured the world's first granite-based concrete that is entirely free of Portland cement and CO2 emissions. This groundbreaking achievement took place at the site of JPMorganChase's new global headquarters in Manhattan, a supertall skyscraper designed by Foster + Partners.
The granite concrete, which was poured on July 8, is a 12 cubic yard slab located on the upper lobby of the building. This marks a significant milestone for C-Crete, following successful pours of other cement-free concretes made from materials like zeolite and basalt.
The use of granite, a non-carbonate rock, offers a significant advantage over traditional Portland cement. While the production of Portland cement contributes approximately 8% of global CO2 emissions, granite-based binders emit no CO2 during manufacturing. This is a major step towards reducing the construction industry's environmental footprint.
Despite being cement-free, C-Crete's granite-based concrete exhibits comparable or even superior performance to traditional concrete. It has a compressive strength exceeding 5,000 psi, is pumpable and workable, and meets ASTM International standards for mechanical and durability properties. Importantly, it maintains cost-parity with conventional concrete, making it a viable alternative for large-scale construction projects.
C-Crete Technologies' commitment to sustainable construction is evident in their focus on developing innovative materials with ultra-low or negative CO2 footprints. By replacing traditional Portland cement with granite, the company is paving the way for a more environmentally friendly future for the construction industry.
