And in some ways you need a decent strength concrete
for a shed floor so you get a decent long lived surface
unless you want to put old carpet on it like some do.

Most of the UK has sand and gravel quarries fairly close, so ballast (a
mixture of sand and gravel) is as cheap as anything else.

Possibly false economy, but then again I think you have more coal fired
power stations than we do.

Fly ash is very fine (not like an aggregate). I assume that you need the
lumps for strength.

I remember it being packed down beside a concrete gully under a dual
carriageway because it was very light and could be compacted to exert very
little side pressure on the concrete.

Also at one time proposed for spreading on marine oil spills to clump up
the oil.

As far as I know modern power stations grind the coal up very fine to make
it burn more efficiently so you probably don't get slag any more.

Cheers

Plastic pallets are free here, and don't rot. As for cheapest agg, just ask your suppliers.

Very few pulverized fuel (ground coal) fired stations now running in the UK due to being sacrificed on the altar of greentardery. Those that were best for concrete quality pulverized fuel ash or PFA (eggborough, Fiddlers Ferry, West Burton, Ironbridge and Longannet) required at least 3 days under baseload for the combustion to settle down and yield low carbon clean pale ash which could be used as a Pozzolan in the mix. Some of the ash particles in the flame would clump together and fuse then fall to the bottom of the furnace. This was Furnce Bottom Ash or FBA colloquially known as Clinker. Used in Breeze blocks and roads.
Adding pozzolan to concrete had many technical advantages. Thousands of tons were included in the Thames barrier and motorway bridges in the South West where alkali silicate reaction in mixes using local aggregate caused failure (concrete cancer).

PFA is an example of "a" pozzolan.....others exist...

A local clay quarry has a housing estate built over it and it was filled by
that black klinker slag stuff then concreted over. I note its starting to
sink now after 50 years.. Oops.

You sure you want to mix it by hand instead of getting a minimix truck
load ?

And in some ways you need a decent strength concrete

unless you want to put old carpet on it like some do.
I have two cement mixers and plenty of time.

Sure, but its quite a bit of work even just for a shed floor.

But a lot easier to get a minimix load and a lot better
quality of concrete that wont spall or crumble in use.

I bit the bullet and bought my ballast in 25kg bags.

It was all really the same cost as paving slabs, but at least I didnt
have to move more than the bags of cement and ballast. And getting it
level was easier


If you have access getting tonne bags of ballast delivered is probably
near as good as it gets.

I am not completely destitute I have full pension and a fixed deposit
which returns almost no interest but wasting money on concrete and other
things eats into it and sends me backwards. I try for neutral but am not
