(25 mm) of cracking through caps. 2 Well-formed cone on one end, vertical cracks running through caps, no well-defined cone on other end. 3 Columnar vertical cracking through both ends, no well-formed cones. 4 Diagonal fracture with no cracking through ends; tap with hammer to distinguish from Type 1. 5 Side fractures at top or bottom (occur commonly with un bonded caps). 6 i il T 5 n f lin r i in NOTES: . Compressive strengths determined in accordance with ASTM C39. . Cross-sectional area, diameter and length are standard unless otherwise noted. . Portions of the information contained in this report have been furnished by others. . Cylinders cured in laboratory in accordance with ASTM C31 unless otherwise noted. . Unbonded caps utilized in accordance with ASTM C1231 unless otherwise noted.
