Geopolymer concrete is a new type of green building material, and chloride ion transport is a key factor affecting its service life. Based on the introduction of the chloride ion transport mechanism of geopolymer concrete, this paper summarizes the characteristics and limitations of the test methods for the chloride ion permeability resistance of geopolymer concrete, introduces the interfering factors of the chloride ion permeability resistance of geopolymer concrete, and compares the chloride ion transport mechanism of ordinary concrete and geopolymer concrete. The article concludes by pointing out that the chloride transport model of geopolymer concrete under the influence of single factors such as high temperature, freeze-thaw, and etc. , the influence of alkali admixture and water glass modulus on the resistance of geopolymer concrete to chloride infiltration, as well as the accuracy of the color rendering boundary concentration of chloride ions are still to be further investigated in depth.
