Ambient Temperature Cured One-Part Geopolymer Binder

Geopolymer binder has the potential to reduce CO₂ emissions and energy consumption by approximately 60% and 80%, respectively, and are widely recognized as sustainable alternatives to ordinary Portland cement (OPC). Conventional or two-part geopolymers are formed by a reaction between a solid aluminosilicate precursor and concentrated aqueous solution of alkali hydroxide, silicate, carbonate, or sulfate, that is, two parts in addition to water. Although significant research has been conducted on different aspects of geopolymer technology in India, this One-part geopolymer technology is in the research stage. However, the impracticalities related to handling large amounts of viscous, corrosive, and hazardous alkali activator solutions has put pressure on the development of one-part or “just add water” geopolymers that could be used similarly to OPC.  In one-part mixtures, only a dry mixture is needed in addition to water. The dry mixture is prepared by mixing a solid aluminosilicate precursor with a solid alkali-activator.
