Cylinder fracture types
WebFeb 1, 1974 · Fracture, in the form of a cone, is valuable in showing that the results of the tests actually represent the compressive strength of the concrete cylinder. The results of any other type of fracture are questionable. To our knowledge there is no way to relate a departure from the cone fracture directly to the cause.
