Why do experts use one kind of
explosive for steel columns and
another for concrete columns?
Steel is stronger than concrete, so it
requires a more powerful explosive.
Experts must put explosives in holes
for steel columns but wrap explosives
in mesh for concrete columns
Experts have to blow up steel columns
but use a special strong fabric to break
apart concrete columns
Steel is sharper than concrete, so it
requires much more explosive.
