摘　　要：比较内衬模板布、硅烷浸渍和环氧涂料表面封闭3种防腐蚀措施对混凝土保护效果的影响。结果表明,3种防腐蚀措施均能显著降低氯离子的渗透深度,特别是在内衬模板布试件上施加硅烷浸渍或表面涂覆环氧涂料措施,能进一步降低氯离子渗透深度,提升对钢筋混凝土的保护效果。This study aims to compare the effects of three corrosion protection measures,namely,inner lining template fabric,silane impregnation,and epoxy coating surface sealing,on the protection of concrete.The results indicate that all three corrosion protection measures can significantly reduce the penetration depth of chloride ions.In particular,applying silane impregnation or surface coating with epoxy on inner lining template fabric specimens can further decrease the penetration depth of chloride ions,thereby enhancing the protection of reinforced concrete.
