I'm planning on laying a concrete slab. In an attempt to stop it

1kg of fibre for a couple of cubic metres of concrete? - this is a waste of
time and money...unless you meant a couple of square metres of concrete
(m2)?

If you did mean square metres, then you don't need fibre anyway, so long as
the concrete is at least 100mm thick.
