Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size as opposed to which withstands loads tending to elongate. In other words compressive strength resists being pushed together whereas tensile strength resists tension (being pulled apart). In the study of strength of materials tensile strength compressive The unit strength method was developed utilizing compressive strength testing data compiled from as early as the 1950s on through the 1980s. Simply put the resulting method derived from test data determined the overall assembly compressive strength based on the individual unit strength and the type of mortar to be used in design.
