Concrete PSI Guide
Concrete is measured by its compressive strength in units of pounds per square inch (PSI). Here is a list of PSI ranges for concrete usage.
How is the strength of concrete measured?
Concrete strength is measured in pounds per square inch, or PSI. Unlike steel or wooden beams that use tensile strength, concrete uses compressive strength, or the ability to carry loads and handle compression downwards. Here are some practical ranges for concrete strength.
2500-3000 PSI
Most concrete has a PSI rating somewhere between 2500-3000. Typically, concrete in this range can be used for sidewalks and residential driveways. This is also more affordable than higher strength concrete.
3500-4000 PSI
This range of 3500-4000 PSI is typically used for structural purposes. You'll often see this PSI range reserved concrete beams, footings, slab foundations, and high traffic roads.
4000-5000 PSI
Concrete in the 4000-5000 PSI range is used in large-scale commercial and industrial projects, such as factories and warehouses.
6000+ PSI
Concrete with a PSI rating of 6000 or more is considered high-strength concrete. It is typically found in nuclear power plants, high-rise structures, or infrastructural projects such as bridges. High-strength concrete also has a lower water-cement ratio, giving it additional durability and strength.
