Influence of the C-S-H Amount on [Cl - ]/[OH - ]Ratio of Sim

发布时间：2021-07-03 08:32

　　Two kinds of simulated concrete pore solutions（SPSs） were treated with different amounts of synthetic calcium silicate hydrate（C-S-H）. The variation of the [Cl^-]/[OH^-] ratio in SPS was measured and the corrosion susceptibility of carbon steel in the SPS was investigated with potentiodynamic polarization, EIS and weight lose tests. The experimental results showed that for the SPS at p H 12.5, as the amount of C-S-H increases, the [Cl^-]/[OH^-] ratio incre...
