Reducing Environmental Impacts of Cement and Concrete

Aug 30,  · Yet producing the portland cement that binds concrete together is energy intensive and emits enormous amounts of carbon dioxide (CO 2) as well as numerous other pollutants. Fly ash can replace a percentage of portland cement in concrete, thus reducing the impacts of concrete while using a material that would otherwise be landfilled.

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.
