来自海洋和海风的氯化物是海洋环境中腐蚀的主要来源，它们在混凝土中的分布通常被建模并用于预测目的。然而，如果在若干时间段内不清楚环境因素（例如相对湿度、温度、风、雨和干燥期）对这种剖面的作用，则可能得不到可靠的结果。虽然这些局限性在一些作品中得到了承认，但文献中很少有现场和孤立的数据来解释和支持，根据不同的暴露条件和时间段，氯化物分布的形状和意义。任何预测模型只有在了解并融入这些信息后，才能获得更高的可靠性。这项工作提出了浓度分布，这是从混凝土暴露于不同的小气候，并讨论了他们的行为和意义，根据环境参数，具体的二元性和几个时间段。(C)2001爱思唯尔科技有限公司版权所有。
The chlorides from the sea and marine breeze are the main source for corrosion in marine environments, and their profiles in concrete are commonly modeled and used for prediction purposes. However, no reliable results may be obtained if the action of environmental agents, such as the relative humidity (RH), temperature, winds, rains and drying periods, on such profiles are not well known through several periods of time. Although these limitations are recognized in several works, there are very few field and isolated data in the literature to explain and support, according to different exposure conditions and periods of time, the shape and meaning of the chloride profiles. Any prediction model could acquire more reliability only after knowing and incorporating such information. This work presents concentration profiles, which were obtained from concretes exposed to different microclimates, and discusses their behavior and meaning according to the environmental parameters, concrete duality and several periods of time.
