    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。

    Abstract: Many construction materials are chemically active materials whose structural properties parameters, physical-mechanical properties, etc. need to be determined. By exploiting embedded wireless sensors within these materials from initial wet manufactured state to final solid capillary-porous material assessment of initial and subsequent properties can be established allowing determination of current and future performance of the construction material. Embedded sensors can also monitor lifetime properties to identify performance degradations in the construction material as well as other construction elements embedded within or around the construction material. Further, the data accumulated from initial manufacturing to extended lifetime allows for additional assessments and improvements with respect to selection of construction material mix for a particular project at a particular location and time, improving the assessment of proactive repair and/or remedial work, quality control monitoring, cost reduction etc.

    Abstract: Hundreds of thousands of concrete bridges, buildings etc. and hundreds of billions of tons of concrete require characterization throughout the process from manufacture to pouring and curing and on throughout service life. The characterization may relate to initial concrete properties, projected concrete properties, framework removal, corrosion, failure etc. Accordingly, a variety of measurements such as water content, electrical resistivity, and half-cell corrosion potential for example would be beneficially implemented as easy to use field test equipment or embedded sensors allowing lifetime monitoring to be performed rather than discrete assessments when issues become evident.
