Concrete is made from cement, sand and aggregate. When mixed with water it hardens to form concrete. The strength of the concrete is measured in pounds per square inch or psi. The psi of concrete is listed in a number on the bag. For example a Quikrete bag may say 3500 or 5000. That number refers to the psi strength of the concrete. The ingredient ratios can be adjusted to make different strength concrete. Concrete is most commonly sold by the cubic yard, but it’s also available in pre-mixed bags like Quikrete or Sakrete.
