Actual Concrete Mix Ratios For 3000, 3500, 4000, and 4500

The actual weights used to make 4.5 yards of 4000 psi concrete are: 1. Cement = 2810 pounds. 2. Stone = 8250 pounds. 3. Sand = 5620 pounds. THIS GIVES YOU A BASIC 4000 PSI CONCRETE MIX RATIO OF: 1 PART CEMENT; 2.93 PARTS STONE; 2 PARTS SAND; Rounded off it's basically a 1 : 3 : 2 mix ratio. If I break the weights down per cubic yard of concrete, it comes to: 1.

Concrete curing time & psi - Fine Homebuilding

Well, Jeff, I'm not in the concrete industry so I can't speak scientifically, but as a contractor it seems the difference is mostly in the amount of cement in the mix (pea-gravel 6-sack mix is 2000 psi, 6-1/2 sack is 2500 psi), but I believe the aggregate size affects strength as well; 1" gravel is what L.A. Public Works requires for sidewalks and curbs.
