ASTM C472 is a standard test method used to evaluate the physical properties of gypsum, including gypsum plasters, gypsum concrete, and related materials. 

This method is used to determine compressive strength, which relates to how these materials perform in construction applications. The test is conducted using a CON Hydraulic Testing Machine, which applies controlled pressure to measure the material’s resistance to compression.
