The cement that built Rome and Athens 2000 years ago is still standing today because it is stronger and more durable than our current (Portland) cement, which is a major source of carbon pollution accounting for about 8% of global carbon emissions.

Pozzolanic cement was replaced by Portland cement almost 200 years ago because Portland cement sets faster in one day than Pozzolanic cement.

Green Cement reengineered pozzolanic cement to make it react faster – matching the one-day performance of Portland Cement. Green Cement products are stronger than Portland Cement in 28 days and continues to gain long-term strength while reducing carbon emissions by 95% and lowering the embodied carbon in the final concrete materials dramatically.
