Concrete Grade Types

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 or greater. Get price
