<p>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.</p> |
