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.
Claims21
A method comprising:
- providing a sensor disposed within or for disposal within a batch of a material comprising:
- a shell comprising an outer surface, an interior, and a pair of outer electrical contacts disposed on the outer surface and coupled to a pair of inner electrical contacts on the interior of the shell;
- an electrical circuit disposed within the shell and comprising a battery, a wireless transceiver, a memory, and a microprocessor;
- a measurement circuit coupled to the microprocessor disposed within the shell coupled to the pair of inner electrical contacts and providing a predetermined electrical measurement of a characteristic of an environment adjacent to the pair of outer electrical contacts;
- wherein
- the microprocessor establishes in dependence upon the predetermined electrical measurement of the characteristic of the environment a current value for the characteristic of the environment and stores the current value within the memory.
