Ballast is OK for small, non-critical jobs, but because it's a get-what-you're-given mix of sandy bits and stony bits, there's no real control over the ratio of fine to coarse aggregate, so you get a highly variable concrete.
Those of us lucky enough to live in parts of the nation with good aggregate supplies, never use all-in ballast. It seems to be restricted to the agg-poor SE of Eng-er-land, but, due to the spread of national DIY sheds, it does occasionally make an appearance beyond its natural home.
As long as they don't start distributing that god-awful hoggin stuff - that should never be allowed out of the SE!
