Compressive strength Wikipedia

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
