Metal mold for manufacturing concrete test piece for traceability and quality control operations of concrete casting in e.g. building, has bottom formed with opening to receive expulsion unit, where opening is sealed by closure unit

摘要

The mold (1) has a cavity (2) defined by a peripheral wall (3) connected to bottom of the mold. An internal face (30) of the peripheral wall is partially inclined at an angle relative to a plane perpendicular to the bottom so as to define a clearance angle for allowing release of a concrete test piece from the mold without disassembling the mold. The bottom comprises a crossing opening that is arranged to receive an expulsion unit of the test piece from the cavity, where the crossing opening is sealed by a removable closure unit.
