Overview of Geopolymer Cement

Source

The chemistry and molecular structure of geopolymers and their engineering behavior are reviewed, in part by comparison to hydrated Portland cement. The geopolymers form by reaction between a solid aluminosilicate and an aqueous alkali hydroxide solution. The reaction involves gelation and the product is an aluminosilicate comprised of silica and alumina tetrahedra linked in three dimensions. Engineering behavior is similar to that of hydrated Portland cement. Set time and strength depend on the reaction chemistry. Durability is generally seen to be good.
