Muck Clamp Concrete Base

[Ukjay]

Hi

I am nearly ready to order the concrete for a muck heap I have been setting out to place our horse muck, and I am not sure what grade I should order.

The steel uprights are almost in (got 3 left to insert), and the base we are laying to mount concrete panels is 7.2 mtr long x 5.5 mtr wide, whereby I will be laying 200 mm thick concrete (just under 8 m3), over a 200 mm base of compacted sub base. It will have some reinforcement sheet added, propped up on those upstand things, so any advice on concrete grade to use would be appreciated - any additives etc!

Kind regards

Jay

RC 32/40 is the kiddy for muck heap floors. Put poly on top of the sub base. Stops the concrete drying out so quick and cracking. The up stand things are called chairs or the little concrete ones are biscuits!

I thought we called them house bricks in these parts!?

Thank very much - will they ask me about any additives, or size of ballast etc - or is that all factored into the RC 32/40?

That made me laugh!

Its all factored in but say what it is for and they may suggest an additive but usually thats the mix for that sort of application.

Rc45 is what we generally use where muck / slurry is involved.

And now the spanner in the works

When I have asked them before - they give the "we cant specify" speach due to possible come backs.

I would change supplier then. We use Smiths or Breedon and they could not be more helpful!

What are you paying per m3 for 30,35 and 40 out of curiosity?

@Ukjay RC40/45 is what your after about £2 a cube difference normally

We have had rc45 specked on drawings for slurry jobs. Recently I asked the question whether rc45 was overkill but was advised by Enstone Breedons technical dept it was what was required. I find them to be very helpful I think we paid £78 per cube on our last job but would need to check invoices

Ask to speak to a rep, whos job it is to advise, Horse muck needs a very high spec.

£78 a cube I can barely get ballest for that here!

So would 45 be needed for stables too then or only areas where a full on muck storage area was going to be?

Both really.

We have laid 16m3 yesterday of rc40/45 with fibres at 150mm thick on a cow yard with heavy vehicles access. It always makes me curious,when I ask how long before we can travel on it or let cows on it ? We pay £86/m with fibres.

As ever, the strength you paid for will be there in 28 days, it will be strong enough for light use earlier obviously, but give it 2 weeks. You could have had 48 hour stuff but it would have been way more than £86.

rc 45 with fibres in is a general spec where muck/slurry is involved the better spec of the concrete is tolimit the crack width (concrete is meant to crack you just design a "max crack width") by reducing this (to well less than a mm probably less than 0.1mm is the spec it stops the ingress of "organic" compounds
