Abstract

Nondestructive exploratory tests of corrosion of steels embedded in water, rubber, cement and soil were carried out by microwave radar measurement. The possibility of these tests was investigated by its simulation (theoretical analysis). The time at first peak of reflection wave (tp) of corroded steel delayed in comparison with that of uncorroded one. The experimental data of tp and its delay time (Δt) corresponded to the calculated ones by simulation. It is thought that from the embeding conditions of steels, i.e., 1) ε, 2) tan δ and 3) thickness of media and 4) ε and 5) tan δ of corrosion layers, and the relation with Δt and thickness of corrosion layer, the degree of corrosion of embedded steels can be predictable by measurements of Δt.
