Partner Call open until: March 18, 2026
Project Start: March 2026
The objective is to develop and validate a wireless sensing system for monitoring chloride-induced corrosion in concrete structures. The system will integrate sacrificial (non-reversible) resistive corrosion sensors positioned at defined depths in construction elements. Sensor data will be collected wirelessly at specified intervals (e.g., annually) to track changes in sensor conductivity caused by corrosion.
By evaluating the loss of conductivity of individual sensing elements over time, the depth of chloride penetration and resulting corrosion can be determined enabling early detection of concrete corrosion for advanced structural health monitoring in construction.
The main challenges are associated with sensor material failures, the alkaline properties of cement during integration, and cross-sensitivities to other influencing factors, such as mechanical stress, temperature cycling and humidity. Furthermore, the correlation between sensor corrosion and real-life effects on concrete health must be studied. Particular focus is placed on thorough sensor material characterization, including highly accelerated life testing.
The project will deliver the functional demonstrator of a compact, wireless sensor for the integration into construction elements for early detection of concrete corrosion. The qualification of the approach will be confirmed by extensive laboratory tests.
