A startup called C-Crete with several patents has claimed the pouring of a new round of concrete — this time granite-based and without the incorporation of Portland cement and any CO2 emissions, at a building site in Manhattan.

The pour at 270 Park Avenue was part of the construction of JPMorgan Chase's new global headquarters, designed by architectural firm Foster + Partners and engineered by Severud Associates Consulting Engineers.

C-Crete has developed several versions of its concrete products without Portland cement, including ones based on zeolite and basalt. The search for carbon reduction in concrete is important because it is the source of a significant amount of carbon dioxide emissions in the world.
