摘要： Globally our environment comprises structures built to perform a meet different requirements including residential, commercial, retail, recreational and service infrastructure. Whilst, millions of tons of construction materials are deployed annually the quality control procedures in many instances have not changed to reflect today's demands. Accordingly, it would be beneficial to provide construction companies, engineering companies, infrastructure owners, regulators, etc. with means to automated testing/characterization of construction materials during at least one of its manufacture, deployment in construction and subsequent infrastructure life. It would be further beneficial for such automated methods to exploit self-contained data acquisition/logging modules allowing them to be employed with ease at the different points in the life cycle of a construction material and/or construction project.

摘要： 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.

摘要： 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.
