WebGeopolymeric cements are particular examples of ´alkali-activated pozzolanic cements´ or ´alkali-activated latent hydraulic cements´. All alkali-activated cements tend to have lower embodied energy/carbon footprints than Portland cements (up to 80-90% but this is pozzolan dependent). WebPozzolana Portland cement is an environmentally friendly cement because the materials used in construction are made from natural recycled waste. It is a very good cement when it is used for plastering works. Pozzolana has silica content that makes it cheaper and therefore reduces the cost of cement.
