Detection of exposed steel in the surface of reinforced concrete |
摘要 |
A method for detecting exposed steel in the surface of reinforced concrete, comprising the steps of: moving an electrode across an exposed surface of said concrete; connecting said electrode to one terminal of a power source; connecting the other terminal of said power source to the reinforcement of said concrete; said power source providing a high voltage current effective to produce a spark across an air gap occurring when exposed steel is detected, said spark initiating a means to signal the occurrence of said exposed steel.
