- Abstract:
- Through indoor accelerated chloride ion erosion test, chloride ion concentrations in concrete with GN salt erosion inhibitor and without salt erosion inhibitor at different depths and erosion time was tested. The impacts of GN salt erosion inhibitor on chloride diffusion coefficient and surface chloride ion concentration of concrete were researched. The reduction coefficient of chloride diffusion coefficient and surface chloride ion concentration of concrete were introduced to quantitative evaluate the effect of salt erosion inhibitor. The results show that GN salt erosion inhibitor can reduce chloride diffusion coefficient by 31.3% and can reduce surface chloride ion concentration by 22.67%. GN salt erosion inhibitor can increase service life of power transmission and transformation foundation structure in large extent in chloride ion environment.
