BS EN 12390-11:2015是一种测定单向非稳态氯化物扩散和扩散的方法 硬化混凝土条件试样的表面浓度。该测试方法启用 测定特定龄期的氯离子渗透性，例如通过对比试验对混凝土质量进行排名 测试。因为抗氯离子渗透性取决于老化，包括持续老化的影响 那么排名也可能会随着年龄的增长而变化。本试验程序不适用于表面处理过的混凝土，如硅烷，也可能不适用于 含有纤维的混凝土（见E.1）。交叉引用:EN 12390-2EN 14629ISO 5725-1EN 12504-1购买本文件时可获得的所有现行修改件均包含在购买本文件中。

BS EN 12390-11:2015 is a method for determining the unidirectional non-steady state chloride diffusion and surface concentration of conditioned specimens of hardened concrete. The test method enables the determination of the chloride penetration at a specified age, e.g. for ranking of concrete quality by comparative testing. Since resistance to chloride penetration depends on the ageing, including the effects of continual hydration, then the ranking may also change with age.The test procedure does not apply to concrete with surface treatments such as silanes and it may not apply to concrete containing fibres (see E.1).Cross References:EN 12390-2EN 14629ISO 5725-1EN 12504-1All current amendments available at time of purchase are included with the purchase of this document.
