Concrete strength - Calculation for slab

[mauricehillier]

Hello, first time of posting, so if in wrong forum please advise.
I have to put up a 92,000L vertical water tank in a farm onto a concrete slab. The Fibre Glass tank is 4M x 7M. I'd prefer to use a fibre reinforcement.

Where should I look for the strength of concrete required?

many thanks, Maurice Hillier

Structural engineer will give you exact advice that's backed if it fails, manufacturer will also give you advice from experience,

I'd say that 92000l = 92 tons of baring pressure

So you want a good 250 mm slab with 2 layers of a193 mesh on good ground or compacted hardcore. This is only advice and no liability assumed haha go get a structural engineer to tell you.

But I'd use c35 for piece of mind
