If you are buying concrete, why do you want sand and rock?
I'm not sure if I'm using the words right.
I'm getting rather confused here.
You want something to hold it to the slab, right?
That something is mortar. Could be Type N mortar...
could be Type S mortar...could be thinset

In another thread, I confused everyone by being wholly ignorant about the

I think you really need to get yourself down to the local library and get a
good book.
It's pointless troubling your head about these matters without a basic
grounding.
If you find something in the book you don't understand get on here

Or go to Wikipedia which is good on technical topics.
