Compressive strength
Know More

Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled ....
