Green cement? Why is it more durable?
Buildings built in Rome and Athens 2,000 years ago are still standing today, using pozzolana cement, which is stronger and more durable than our contemporary Portland cement.
Pozzolana cement was replaced by Portland cement about 200 years ago because Portland cement sets faster than pozzolana cement in a day.
Portland cement is one of the contemporary sources of carbon pollution , accounting for approximately 8% of global carbon emissions.
Green Cement redesigns pozzolan cement so that it reacts faster - on par with the one-day strength of Portland cement.
Green cement products are stronger than Portland cement within 28 days and continue to gain long-term strength while reducing carbon emissions by 99% and significantly reducing the carbon content of final concrete production.
Compared with modern Portland cement, it has the following obvious advantages:
Green cement products reduce Portland clinker demand by 50-100%
Resistant to sulfate and alkali silicon reactions
Reduces the heat released by the hydration process, making concrete pouring easier
Excellent strength properties - 20% strength increase in 28 days
