Abstract

ASTM C1550 has been used for post-crack performance assessment of fiber reinforced concrete (FRC) and shotcrete (FRS) for several years and has proven to be an excellent tool for quality control testing due to the very low level of within-batch performance variability typically obtained using this test method. Experience in the field indicates that the positions of the three radial cracks generated in a test vary between specimens and concerns have been raised by users of this test that specimen performance may change as a result of this variation in crack location. The significance of this aspect of specimen behavior has been investigated to determine the characteristic range of crack rotations experienced in C1550 specimens as a result of variations in crack location and the magnitude of their corresponding influence on post-crack load resistance.
