Abstract

The fly ash-based geopolymer concrete (FAGC) were prepared by using fly ash as the main binder. The influences of curing conditions on mechanical properties and permeability were investigated by compressive test, flexural test and permeability test. The results indicate that elevated temperature curing accelerates the early reaction of FAGC, which is conducive to its early strength. Proper steam curing is beneficial to the early flexural strength of FAGC. While the flexural strength decreases under a long-time and high-temperature steam curing. Elevated temperature curing is bad for the strength development of FAGC. The strength increases slowly under a long-time and high-temperature steam curing. This is related with the decreased compactness and porous structure degradation caused by elevated temperature curing.
