How many sacks of cement makes 3000 psi?

The number of sacks of cement needed to achieve 3000 psi concrete can vary based on the mix design, but a typical guideline is using one sack (94 pounds) of cement per cubic yard of concrete. For a standard 3000 psi mix, you might use around 5 to 6 sacks of cement per cubic yard, depending on the aggregate size and water-cement ratio. It's crucial to follow specific mix designs for accurate results. Always consult a concrete mix design guide or an engineer for precise formulations.
