I have a slab of 130.4 m by 12 cm. How many bags of cement weighing 50 kg ai - I Need? How many bars of iron diameter 12, 10, 8 and 6 will I need? How many tons of sand? How many tons of gravel and what size? I'll be very glad if someone can help me for this. Thanks in advance

Any of First Hi, yes this is important! 130m Â² 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
