Geopolymer cement - Wikipedia

It is a more environmentally friendly alternative to conventional Portland cement. It relies on minimally processed natural materials or industrial byproducts to significantly reduce the carbon footprint of cement production, while also being highly resistant to many common concrete durability issues.. Geopolymer cements exist which may cure more rapidly than Portland-based cements.
