### What Are the Different Grades of Concrete? Reference

What Are the Different Grades of Concrete? Concrete grades are determined by concrete's compressive strength 28 days after it has been poured. The strength is measured in psi, or pounds per square inch. The greater the psi rating on a mix of concrete, the stronger the concrete will be after it has been poured and set. The required strength of
