FRACTURE TYPES:
1 Reasonably well-formed cones on both ends, less than 1 in. (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 unbonded caps).

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 C 1231 unless otherwise noted. Because of the violent release of energy stored in pads,
the broken cylinder rarely exhibits conical fracture typical of capped cylinders and the sketches of types of fracture in Test Method C39 are not descriptive
. Samples taken in accordance with ASTM C172 where practicable' When applicable, the following test procedures were used: Slump ASTM C143;
Unit Weight ASTM C138; Air Content ASTM C173/ C231; Temperature ASTM C1064
