A sustainable ambient temperature cured “dry-mix” geopolymer composite is developed. The developed geopolymer composite exhibited comparable performance to SHCC M45. High tensile strength (4.6 MPa) and very high tensile ductility (4.2%) were achieved. The developed geopolymer composite offers 76% less carbon emissions than SHCC M45. The developed geopolymer composite offers 36% less embodied energy than SHCC M45.
