The Importance of Monitoring Construction Materials
The TEM is based on electronic measurement of chemical reactions that reveal the penetration of corrosion inside the concrete.
The TEM sensor inserted into the concrete structure through a small hole, injects a solution and measures the half-cell potential with respect to a counter electrode of liquid junction of the type Cu/CuSO4 (sat. sol).
It analyses two parameters:
1. Chlorides concentration and distribution
2. Concrete pH and carbonation depth
