Being it is a uk group it seems reasonable to suppose that UK meanings
are generally intended. It will probably make your comments more useful
if you find out what we are talking about first, before contradicting.
Just a suggestion. And you simply can't make good concrete without a
reasonable amount of fine sand-sized aggregate, wherever you get it
from.

Having always assumed the term came the most convenient material for
stabilising unloaded vessels, I was curious enough about the origin of
the term to look it up.

Not very helpful.



Ah.. i had also assumed this usage started from ballasting empty
sail ships for return voyages.... maybe even to the Antipodes?
How ironic! :-)
