Concrete strength: what is the compressive strength of concrete the strength of concrete is measure in terms of pounds per square inch (or psi). psi is a measure of compressive strength, or the ability of the material to carry loads and handle compression.

Concrete with a psi rating of 6000 or more is considered highstrength concrete. it is typically found in nuclear power plants and other areas where radiation contamination is possible. high strength concrete has a lower watercement ratio, giving it additional durability.
