An environmental evaluation of geopolymer based concrete ...

This is due to the heavy effects of the production of the sodium silicate solution. Geopolymer concrete made from fly ashes or granulated blast furnace slags based require less of the sodium silicate solution in order to be activated. They therefore have a lower environmental impact than geopolymer concrete made from pure metakaolin.

Ecofriendly geopolymer concrete: a comprehensive review ...

2021-4-16  After ordinary Portland cement (OPC) concrete, geopolymer concrete (GPC) is the most advanced form of concrete. GPC has many advantages including improved strength and durability properties. High early age strength and ambient curing of GPC helps to reduce the construction time. Factors such as binder materials, alkali-activated solution, and curing methods control GPC’s strength

2021-8-11  Geopolymer Cement Concrete. Concrete is a general term used to describe a mix of different sized aggregates (such as sand and small rocks) held together in a matrix by a binder, also called a cement. Concretes are mixed wet and then dry to form a hard, durable material. The binder used in conventional concrete is called Portland cement.
