Every 80lb concrete bag should be mixed with 4 quarts or 3.7 liters of water. This mixture will allow you to place aproximately .60cu/ft of concrete. There are 27 cu/ft in a cu/yd. The number then becomes .0222 yards per 80lb bag. Therefore 45 bags of 80lb (4000 psi) concrete ready mix will be enough for 1 yard of concrete.
The weight of a concrete 80 lb bag is 80 pounds.
