fr Indice traduisant la fragmentatibilité d'une roche sous l'effet d'une usure mécanique. Il correspond au rapport de la masse initiale d'un échantillon de roche sur la masse des fragments de moins de 1,6 mm de diamètre, produit par la rotation de l'échantillon dans un cylindre avec une charge abrasive.
