氯离子侵入钢筋混凝土中会导致钢筋锈蚀。本文讨论了一种近场微波方法检测氯离子侵入砂浆暴露于循环氯离子溶液。砂浆标本暴露于自来水，作为对照，和氯化物溶液的2.8%的盐度。3 GHz下的每日微波反射测量清楚地表明暴露于氯化物的样品中氯离子的进入。两个电磁建模方法，描述了暴露于自来水的试样与微波信号的相互作用进行了讨论。
Intrusion of chloride ions in steel reinforced concrete may lead to corrosion of steel reinforcement. This paper discusses a near-field microwave approach for detecting chloride intrusion in mortar exposed to cyclical chloride solution. Mortar specimens were exposed to tap water, as a control, and to a chloride solution of 2.8% salinity. Daily microwave reflection measurements at 3 GHz clearly indicated the ingress of chloride ions in the sample exposed to chloride. Two electromagnetic modeling approaches that describe the interaction of microwave signals with the specimen exposed to tap water are discussed.
