ASTM C1550 requirements create new challenges for testing flexural toughness of fiber reinforced concrete including a larger specimen size and required stiffness.
ASTM C1609-10 specifies how to determine the peak strength of fiber reinforced concrete as well as the residual strength after a crack is created.
ASTM C99 specifies a method to determine the modulus of rupture for dimension stone, such as granite, marble, limestone, and sandstone.
