低频阻抗模值(|Z|0.01Hz)图: (a)在钢筋表面制备最佳ZIF-8添加量的Ce-Sol-gel膜在0.1 M NaCl的混凝土模拟浸泡20天; (b) 将钢筋嵌入水泥泥浆中养护28天后在3.5 wt. %NaCl中浸泡20天。
The low-frequency impedance modulus (|Z|0.01Hz) is shown as follows: (a) Ce-Sol-gel film with the optimal amount of ZIF-8 was prepared on the steel bar surface and simulated soaked in concrete with 0.1M NaCl for 20 days; (b) The rebar was embedded in the cement slurry for 28 days and soaked in 3.5 wt. %NaCl for 20 days.
