Each time pin penetration test requires a new pin as the pin gets blunted after use. The strength properties of mortar and aggregate affect the penetration depth of the probe in the concrete. These strength properties are different than they are in crushing strength of cube, wherein the strength of mortar continuously governs the strength.
