Which concrete mix

[tullah]

I want to concrete a base for a shipping container 9 metres by 2.4 metres to sit on. Container would be storing 16 tonnes water in tanks plus basic container weight.
It would be sited in the yard which already has a hard base. What mix would I need to order and what depth concrete would I need? Thanks in anticipation.

RC40 grade mix poured at least 6" deep, with A252 mesh should see you.

You could skimp and go 4" and lower gauge mesh (A193), but for the limited cost increase I would go for something a bit deeper and stronger.

That's a strong mix for something which isn't going to be moving. Would say you could get away with a C30 mix on a hard standing yard

Could I get away with the C30 mix and 5" thick with no steel?

Really depends on the situation, if there is no traffic then you don't need as strong a mix.

Order your concrete through a firm with volumetric wagons, that way you can decide when they turn up!

You could just put a base at each corner if you wanted to save some money!

Save more money and put it on sleepers.

Concrete corners and sleepers is way I'm going. Thanks

5" of 30 plenty for that 40 with mesh is for heavy traffic.

How much cement in a cube of c40 ??

Would have to ask the professor tomorrow but would guess on a C40 at about 150-175kg??

I'd of thought you could double that figure at least.... I may be wrong though!

Normally a minimum of 400kg

I have containers sat on bits of wood for 30 years. Still not sunk!!! Save your money.
