The paper describes the studies conducted on heat-cured low-calcium fly ash-based geopolymer concrete, dry and steam-cured at 60 degrees C. Extensive test data are used to identify the effects of salient factors that influence the properties of the geopolymer concrete in the fresh and hardened states. These results are utilized to propose a simple method for the design of geopolymer concrete mixtures. Test data of various short-term and long-term properties of the geopolymer concrete are then presented. The last part of the paper describes the results of the tests conducted on large-scale reinforced geopolymer concrete members to illustrate the application of the geopolymer concrete in the construction industry. The economic merits of the geopolymer concrete are also briefly mentioned.
