What is the ratio sand to cement?

I am mixing concrete for a small slab.


Answer by  Ranjan (159)

It depends on the structure, but for the common purpose the ratio should be 1 to 4 meaning 1 pack of cement to 4 packs of sand.

One part cement to three parts sand. If you want to add gravel to your mixture add three parts gravel to your cement to sand mixture.
