Concrete with Static Electric Buildup

[DaveFlax]

I have been told that some concrete floors will have high static buildup and people will get shocks if they touch metal object while walking on them. I have been told that this high static buildup is due to the rebars and to aggregates with high iron contents. This does not make much sense to me. Has anyone else heard of this and are the rebar and stone really the culprits? Thanks.

Almost any floor will contribute to a static charge when walked on. Has nothing to do with the rebar.

actually there exists a proprietary paint which can be applied to the concrete surface to render the concrete anti static. a good knowledge of the amount of ohms one requires to resist will help in establishing the right paint thickness requirement.
