摘要：

The three key oxide molar ratios of geopolymer concrete were studied in this paper: n(SiO2)/n(Al2O3), n(Na2O)/n(Al2O3) and n(H2O)/n(Na2O). The effect of each oxide molar ratio was assessed by electric flux method. It was found that resistance to chloride ion of geopolymer was increased with increasing n(SiO2)/n(Al2O3). However, there was a limit beyond which this performance improved; it performed better with the increasing of n(Na2O)/n(Al2O3) but worse with the increasing of n(H2O)/n(Na2O). With the same amount of cementitious material, resistance to chloride ion of geopolymer concrete was better than that of common concrete.
