Can I mix hardcore to make concrete??

Post by neilianos » Sun Sep 09, 2018 5:22 pm

I've got a ton bag of hardcore left, and have a few holes in a stable floor need filling. Can I use this or do I really need to use sand n gravel?

:welcomeuhm:

It depends how deep are the holes you got to fill and you will still need a lot of sand (and then you might add some gravel in the mix too). You can mix any materials you want but effectively you must have stone for strength and finer stone (sharp sand) to fill the gaps.

I've seen all sorts used to make concrete and as it's just for a few holes in a stable floor probably not going to be a problem although you'll be better off getting some sand to mix in too. I'd look at the size of the hardcore too , ideally for concrete you don't really want anything bigger than 20mm.

I actually did this week end, hard core too big for this hole I wanted to fill in, used the above perfect fit now.
Fret not, a forum is a collection of opinions. Above, are mine.

Which is correct? Metre or Meter? Click the link to find out more.

Working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe?

I had a load of mixed size aggregates and stones and thought the best way to get all the same size would be to riddle it. I had a 10mm riddle and a couple of smaller ones but trying to find a 20mm at a decent price proved awkward so I wove one with some thick fencing wire and attached it to a frame .
