Surface Chloride Ion Concentration Study of Brine Corroded High Performance Concrete (HPC)

Abstract:

4 kinds of mix proportion High performance concrete (HPC) was manufactured, whose material was produced from Inner Mongolia areas. During the brine corroded HPC experiment, the effects on surface chloride ion concentration of HPC, which was produced by different curing age and soak time, were studied. And the resistance to corrosion of HPC was analyzed. The curing period of HPC was adopted as 28d, 56d, and 90d. The soak period of brine-corroded HPC was 1 year. The changes of HPC surface chloride ion concentration were obtained in the experiment. Results show that, in the brine-corroded environment, the surface chloride ion concentration of HPC decreases obviously by the extension of HPC curing period. Furthermore, the surface chloride ion concentration of 4 HPC samples increases by the extension of HPC soak period, whose late growth is becoming gently. In the meanwhile, the regression relationship between HPC surface chloride ion concentration and different curing period, soak period is achieved.
