Abstract
Fly ash-based geopolymer binders and activating solutions for use in forming a concrete as well as methods for forming concrete including the binders are described. The fly ash-based geopolymer binders include a combination of fly ash, silica fume, and sodium hydroxide as well as an amount of Portland cement. Concretes formed of the binders can exhibit excellent compressive strength and fuel energy characteristics as well as being more cost efficient as compared to other concretes. The inclusion of an amount of Portland cement in the binders can allow for a decrease in sodium hydroxide and silica fume content while maintaining desirable compressive strength characteristics.
