Bill,
Not unless the lightning hits the concrete directly, in which case, all
bets are off A direct strike can be like getting hit by an artillery
shell. .
The theory that lightning currents conducted through concrete will the
moisture to steam, causing an explosion, is unfounded. Concrete can make
a very important contribution to lightning grounding. Look up "Ufer
grounding" for the details. Interesting background.
