What PSI is ready mix concrete?

Concrete mix designs can produce strengths in excess of 12,000 psi (pounds per square inch) for high rise applications to mixes with as little as 50 psi, which can be used as back fill and easily dug up and removed by the contractor later.

What is 3000 psi concrete used for?
