(*) Test carried out according to the Wide Wheel Abrasion (capon).

Caption/Table legend: Patm: Atmospheric pressure; 56c: 56 cycles of freeze-thaw; ρb: Apparent density; p0: Open porosity; Ab: Water absorption; Rtf: Mean value of Flexural strength under concentrated load; EL (Rtf): Lower expected value of Flexural strength under concentrated load.

Granite has been tested in the CTG laboratory. The results of these tests are only related to the samples tested.
