How many bags of Portland Cement for a CU Yard?
They are 90lb bags. From what I recall, it was 3 bags per cu yard.
Yet I got this guy at the local lumberyard who insists I need 5 bags
per... Sounds to me he is trying to make more money...

I am referring to a standard mix of 1 part portland, 2 parts sand and
3 parts stone.

It's been awhile since I made cement so I am asking to be sure. I'm
checking into the cost to make my own from scratch rather than truck
in some ready mixed stuff in a tub.
