Rebar properties

[bleps]

We are looking for electrical data on rebar; specifically, the electrical resistance of #3, uncoated.

Don't know the answer. How tough would it be to test it ?

RWF7437,

I wouldn't think it would be that hard to test.

Depending on the level of accuracy required, you could test a given length with freshly cut ends and reduce the length as appropriate to get resistance per unit length data for regression / statistical analysis. Repeat for several samples from different bars/production lots if possible. Properties may vary across different manufacturers if the type of steel alloy varies.

Wouldn't it be about the same as apiece of mild steel?

I would thing that with the surface irregularity, the mix of materials that can go into rebar and with the deposition of these on the outside surface that you might get some 'scatter' in the results. I wouldn't be looking for any real precision.

I would just use the #'s for steel in that diameter. It should give you a close enough average, and then over design.
