What Are the Different Grades of Concrete?

The required strength of the grade itself is largely dependent on its intended use. For most residential uses, the minimum concrete grade is 2,500 psi. Commercial work, on the other hand, will typically require a grade of 4,000 psi or higher. Any type of concrete that is rated higher than 6,000 psi is considered to be high-performance concrete.
