Oct 28, 2013· Specified concrete compressive strength is the minimum compressive strength at which the concrete should fail in standard tests of 28-day-old concrete cylinders. A typical concrete compressive strength specification requires 4,000 to 5,000 psi at 28 days.

The cylinder that broke at 1980 psi is 66% of the specified 3000 psi. According to Mindness and Young's rule, it should meet the specified strength at 28 days. Most likely, the mix wasn't designed for 3000 psi but for a higher compressive strength to account for variability.

If you are using it on footings and walls, a concrete strength of 2,500 psi could be enough while between 4,000 to 5,000 psi is needed for pavements. Outdoor concrete used on home improvements should be ordered with a strength ranging from 3,500 to 4,500 psi.

The minimum strength that should be specified is 2,500 psi (17 MPa). A slightly higher compressive strength of 3,000 to 4,000 psi (20 to 30 MPa) can help the flowability and pumpability of the concrete and provide additional strength to the walls with minimal or no additional costs. Compressive Strength Chart …

Concrete compressive strength requirements can vary from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 MPa) and higher in commercial structures. Higher strengths up to and exceeding 10,000 psi (70 MPa) are specified for certain applications.
