Along with cement, concrete also contains water, a coarse aggregate, and a fine aggregate like gravel or sand. The strength and durability of concrete is determined mainly by the proportions of the ingredients. Concrete strength is measured in pounds per square inch (PSI) in the imperial system and megapascals (MPa) in the metric system.
