采用快速氯离子渗透试验方法、稳态电迁移方法和电导方法 ，对普通水泥混凝土、轻骨料混凝土及掺粉煤灰、矿渣、硅粉、偏高岭土和稻壳灰的混凝土 进行了氯离子渗透扩散性试验研究.结果表明，混凝土的抗氯离子渗透扩散能力随水灰比的 减小而提高.粉煤灰和矿渣能提高混凝土的抗氯离子渗透扩散能力，硅粉、偏高岭土、稻壳 灰和适当掺量的矿渣能大幅度提高混凝土的抗氯离子渗透扩散能力.在整个通电量范围内， 通电量和初始电流之间并不存在良好的线性关系.

Three methods for measuring the chloride ion permeability were used,a nd the corresponding results were compared.The methods used were chloride perme ability test (AASHTO T227 and ASTM C1202),steady-state migration test and condu ctivity test.The concrete used in this paper included the control Portland ceme nt concrete,lightweight concrete and the concrete containing fly ash,slag,sil ica fume,metakaolin and rice husk ash.Test results indicate that the resistanc e of concrete to chloride ion penetration increases with the decrease of water-c ement ratio.Fly ash and slag can increase the resistance of concrete to chlorid e ion penetration,and silica fume,metakaolin,rice husk ash and some content s lag can increase significantly the resistance of concrete to chloride ion penetr ation.There is not a good linear relationship between the charge passed and ini tial current in the whole charge range.Three tests lead to a similar conclusion regarding the relative qualities of concretes.ASTM C1202 still can be used in many cases,and the conductivity test method appears to be better suited to the chloride permeability test.
