Can Concrete Conduct Enough Electricity for a Shock to Be Felt?

[hackhard]

if i touch the live (single phase) wire , i will get a shock.But current will have to flow through the body , via the floor , walls of the building , and into the Earth .
But cement has electric resistance higher than 1gigaohm
so rms current = 220 v / impedance
impedance > 1 giga ohm
so rms current is in order of nano ampere
how do i get a shock then?

Here's a detailed answer that yes concrete can conduct electrical current although not very well but well enough that someone might feel it as a shock. It conducts via ionic conduction more on it here:

and for ionic conduction:

Its also possible that the concrete could be slightly damp but not noticeable and the water on the surface conducts the current.
