Need Concrete Recipe


If I needed to cover an area of 30 square feet at 2 inches thick using 1-2-3 formula of cement, sand and gravel, how much of each would I need? Cubic units always confuse me so if you could provide both the weight and volume measurements that'd be great, thanks.

9 - 80 pound bags of the pre-mix but 2" is a little thin. Whats it for?

oh yeah, its one part Portland cement, two parts sand and three parts coarse aggregate.

I'm making pavers for a garden path. 1 part cement, 2 parts sand and 3 parts aggregate was actually what I meant by "1-2-3 formula." Would you happen to know the weight and volume value of all the dry materials? I might go with a concrete pre-mix like you suggested but I wanted to see if I could save some money mixing my own.
