Abstract:
A geopolymer concrete mixture based on alkali-activated coal fly ash was developed to provide a viable balance of fresh mixture workability, setting time, and compressive strength (with room-temperature curing). The resulting mixture was used to construct a section of a sidewalk. This and other studies show that conventional concrete construction practices could be used with geopolymer concrete.
