| 摘 要： | 通过室内试验和暴露试验，研究了透水模板布对海工高性能混凝土抗氯离子渗透性的长期影响。结果表明：透水模板布可有效提高表层混凝土的抗氯离子渗透性，降低混凝土氯离子扩散系数，26个月暴露龄期时氯离子扩散系数降低了30％～60％，可显著提高混凝土结构的使用寿命。

| Abstract: | The long-term effect of Controlled Permeability Formwork （CPF） on chloride ion penetration resistance for marine high performance concrete has been studied using laboratory test and exposure test. The results show that the CPF can effectively improve the surface concrete in anti-chloride ion penetration, delay chloride ion penetrating into concrete, reduce the chloride diffusion coefficient by 30 %-60 % at 26 months exposure age, and can significantly increase service life of structures. |
