I understand that acetylene bottles do contain a porous filler - but I've
never heard that it was concrete. One reason for the filler is to keep the
solution from sloshing around - acetylene bottles actually contain a
solution of the gas in acetone. This is because acetone is an incredibly
good solvent for acetylene --- one volume of acetone can contain up to 300
volumes of acetylene (at 12atm pressure). The solution can contain the
same amount of acetylene at a much lower pressure than would otherwise be
possible.
