Concrete is known to be strong and long-lasting, but just how strong it needs to be to do its job varies, depending on the application. The compressive strength of concrete refers to how many pounds per square inch (psi) it can handle when force is applied. It is a reliable indicator of how it will perform under heavy loads or internal ...
