How many shovel of gravel in a 80 pound bag concrete?

The amount of gravel needed for an 80-pound bag of concrete can vary based on the desired mix ratio. Generally, a typical concrete mix might use about 1 part cement to 2 parts sand and 3 parts gravel. For an 80-pound bag of concrete, you would typically use around 0.6 to 0.8 cubic feet of gravel, which translates to approximately 4 to 5 shovels, depending on the size of the shovel and how densely packed the gravel is. Always refer to specific mixing instructions for the best results.
