Experimental Study on the Distribution Law of Chloride Ions of Basalt Fiber Reinforced Concrete Under Gobi Environment
In order to explore the distribution law of chloride ions in concrete under the Gobi environment,the mass fraction of chloride ions in concrete at different erosion depths was measured using the water cement ratio and basalt fiber content as variable.The time attenuation coefficient of concrete with different water cement ratios and basalt fiber contents was normalized by a concrete chloride ion diffusion coefficient model.The influence coefficients of concrete water cement ratio and basalt fiber content were obtained through regression calculation.The research re-sults indicate that the mass fraction of chloride ions in concrete increases with the increase of erosion period.Under the same erosion cycle,the mass fraction of chloride ions in concrete gradually decreases with the decrease of water cement ratio;When the content of basalt fiber does not exceed 0.10％,the resistance of concrete to chloride ion erosion improves with the increase of basalt fiber content.
