We drill and remove only about 2 in. diameter of concrete cover and the bar is at least 2 in. deep. Since the reinforcement is hard to access, we tap a thin steel bar into the reinforcement for convenient connections. So, cleaning is always not perfect.

Thank you, Sir, for your timely help. Fortunately, I do not need more accuracy in the measurements. I am putting together a journal article about our field corrosion testing of a bridge deck, so thought of clearing my doubt about this resistance issue. I used a vice grip to attach the wire to...

Hello, I had to measure the resistance between different sets of bridge deck reinforcement steel bars using a Wavetek HD110T multimeter and a wire. The values varied between 1.9 to 2.8 ohms. When I measured the resistance of the wire itself, it came out to be 2.1 ohm. I could not...
