ASTM C1550 is the test method for the flexural toughness of fiber-reinforced concrete using a centrally loaded round panel. To match this to your program, talk with our team.
What ASTM C1550 Covers
It measures the energy a fiber-reinforced concrete panel absorbs in flexure after cracking, characterizing the post-crack performance that fibers provide for shotcrete and slabs.
How the Test Is Run
A round panel is supported on three symmetric points and loaded centrally past cracking, and the load-deflection curve gives the energy absorbed to defined deflections.
Why It Matters
Post-crack toughness is the key benefit of fiber reinforcement; a frame with adequate travel and deflection measurement is required.
