Corrosion has been identified as the primary cause of premature deterioration of reinforced concrete structures severely reducing the strength and life of structures. There are several methods available for detecting and evaluating the corrosion in reinforcement steel. However, half-cell potential has been recognized by many researchers as the main method to detect the corrosion activity in reinforced concrete structures.
We have based our corrosion monitoring solution on the half cell potential methodology prescribed in ASTM C876 to determine the probability of corrosion rather than the measurement of corrosion. Our solution addresses the practicality and economics of this methodology and focuses on making high quality data available in a structured and visual format for better interpretation by corrosion experts.
Current practice requires the measurement of the potential difference between rebars in concrete and a reference electrode. The measurement is done by physically accessing the measurement points and placing the reference electrodes manually to obtain the potential difference readings. The equipment is unwieldy, accessing points of corrosion risk is difficult and unsafe, and the operation can be expensive. The Smart Structures solution uses reference electrodes that are embedded in the concrete at predetermined locations at the time of construction. The measurement of potential difference and generation of a heat map that represents changes in potential difference over time could soon be as uncomplicated as logging into a website and requesting for the data visualization of corrosion monitoring logs of a specific bridge or structure.
Now that’s a paradigm shift from clambering all over a structure and taking readings point by point.
Infrastructure Asset Management through the lifecycle
The original application of the IP we developed to embed sensors in concrete is the performance measurement of driven piles and drilled shaft foundations. The potential to embed different kinds of sensors in concrete creates the possibility of assessing the performance of structural elements with far greater convenience and addressability than possible with manual inspection. At Smart Structures, we are developing a comprehensive solution for performance monitoring of concrete structural elements through the life of the structure.
