Also missing - the loading footprint and reinforcement. Without that, the number of possible answers is infinite.

Are you expecting to store anything that will impose a load greater than 9000kg on an area 30cm by 50cm? If not, then I would say you have nothing to worry about.

As I said, there are a million different answers depending on the footprint and magnitude of the load and the stiffness of the soil the slab is bearing on. There is no simple equation to determine what the slab can support. The other aspect that adds another layer of complexity is the question of what constitutes failure - cracking? Punching through? The capacity changes by a factor 5 to 10 depending on the answer.
All I can tell you with any degree of confidence, is that if this is an in-place concrete pavement slab that has successfully supported heavy truck traffic, it will support the load of a heavy truck. It's hard to imagine loading as a storage area that would be greater than that.

sholah - agree with HotRod10.
If you have a perfectly uniform loading (kg/m^2 everywhere) the slab can take essentially its material strength which is huge.
What happens is that the soil would settle under load.
If the load is uniform everywhere, and the soil is uniform everywhere, then the soil will settle uniformly and not bend/stress the slab at all.
So HotRod10 is asking about load patterns (i.e. non-uniform loading) and soil conditions (i.e. non-uniform soil stiffness) and many other variables.
There are numerous books and documents "out there" that you can reference such as the few I posted above.
