Description
In order to improve concrete performance in the plastic state, macrofibers are added to the concrete mix to increase the post-crack bending strength. This process improves the capacity of the material to absorb energy after cracking (toughness property).
There are basically two test methods of the American Society of Materials Testing (ASTM) for evaluating the toughness of fiber-reinforced concrete: ASTM C1609 for beams and ASTM C1550 for round panels.
The European Committee for Standardization (CEN) proposes the method EN 14651 for beam specimens and EN 14488-5 for square panels.
