    Abstract: Concrete can be one of the most durable building materials where consumption is projected to reach approximately 40 billion tons in 2017 alone. Despite this the testing of concrete at all stages of its life cycle is still in its infancy although testing for corrosion is well established. Further many of the tests today are time consuming, expensive, and provide results only after it has been poured and set. Accordingly, by exploiting self-contained wireless sensor devices, which are deployed with the wet concrete, the in-situ curing and maturity measurement data can be established and employed together with batch specific concrete data to provide rapid initial tests and evolving performance data regarding the concrete cure, performance, corrosion of concrete at different points in its life cycle. Such sensors remove subjectivity, allow for rapid assessment, are integrable to the construction process, and provided full life cycle assessment.

    Abstract: Hundreds of thousands of concrete bridges and hundreds of billions of tons of concrete require characterization with time for corrosion. Accordingly, protocols for rapid testing and improved field characterization systems that automatically triangulate electrical resistivity and half-cell corrosion potential measurements would be beneficial allowing discrete/periodic mapping of a structure to be performed as well as addressing testing for asphalt covered concrete. Further, it is the low frequency impedance of rebar in concrete that correlates to corrosion state but these are normally time consuming vulnerable to noise. Hence, it would be beneficial to provide a means of making low frequency electrical resistivity measurements rapidly. Further, prior art techniques for electrical rebar measurements require electrical connection be made to the rebar which increases measurement complexity/disruption/repair/cost even when no corrosion is identified. Beneficially a method of determining the state of a rebar without electrical contact is taught.

    Abstract translation: 数以万计的混凝土桥梁和数百亿吨混凝土需要随时间进行腐蚀鉴定。 因此，自动三角测量电阻率和半电池腐蚀电位测量的快速测试和改进的场表征系统的协议将是有利的，允许执行结构的离散/周期性映射以及解决沥青混凝土的测试。 此外，混凝土中钢筋的低频阻抗与腐蚀状态相关，但这些通常耗时易受噪音影响。 因此，提供一种快速进行低频电阻率测量的方法将是有益的。 此外，用于电钢筋测量的现有技术需要对钢筋进行电连接，即使在没有确定腐蚀的情况下也增加了测量复杂性/破坏/修复/成本。 教导了一种确定没有电接触的钢筋状态的方法。
