Concrete Grade Types | Hunker

The grade of concrete is determined by its compressive strength at 28 days after pouring, measured in psi. The higher the psi rating of a given concrete mixture, the greater its strength. Most residential applications require at least 2,500 psi, according to the National Ready Mixed Concrete Association, while commercial work requires 4,000 psi ...

How to Calculate the Load Bearing of Concrete | Hunker

Jul 12, 2017· This note reflects the specific mix you will order throughout your project. Write this number down. This is the base loadbearing strength of your concrete. If you are doing a smaller home project with no special accelerants added to your mix, your loadbearing strength per concrete yard will be 3,000 psi. This is the standard psi of a common mix.
