Effect Of On Graphene Oxide the Concrete Resistance to Chloride Ion Permeability

Abstract

The electrical resistivity test, compressive strength test and RCM test of graphene oxide were conducted to analyse graphene oxide concrete resistivity, cube compressive strength and chloride ion diffusion coefficient changing with the testing age. Then, the quantitative correlation between chloride ion diffusion coefficient and electrical resistivity, cube compressive strength was established. The results show that the compressive strength, electrical resistivity was improved while the chloride ion diffusion coefficient was reduced with the incorporation of graphene oxide. The chloride ion diffusion coefficient decrease with the increase of electrical resistivity, which the two have good inverse function correlation. Then, the chloride ion diffusion coefficient decrease with the increase of the compressive strength. At the same time, they have a good exponential function relationship with each other.
