For your concrete slab
envioron you need 30 tons of mixture (sandy gravel) 0/15 5 tons of cement

2500 liters of water
Caution is an estimate, see for precise dosing with the DTU

To take
reinforcement of welded mesh panels, easy to implement, it should not be put forward, but at 4 cm from the bottom of the slab

Any of First Hi, yes this is important!
130m ² of slab thickness of 12cm, giving a volume of 15.6 m3 of concrete. For a 250kg concrete mix, you will need approximately:
-3.9 tonnes of cement.
-13.3 M3 of gravel 5/25.

-3.5 m3 of sand 0/5.
-1.8 m3 of water.
-130 sq welded mesh.
These figures give you a good idea of what you need, but are not to be taken literally. Everything will depend on your assay. Personal opinion, for such a volume, it is safer to have them delivered concrete. Again, it depends on the usefulness of the slab, but it is more regular and therefore more solid.
Good luck
