Get PriceDetermine the Concrete's Strength. This is normally measured as compression strength, measured by pounds per square inch, or psi. A common bag of concrete, for example, may have a compression strength of 4,000 psi, based on a thickness of 2 inches after it has set for 28 days. Other concrete may have a compression strength of only 550 psi.
