<p>The device for making concrete test bodies uses a cylindrical former with open top and is designed for easier and simpler operation, separation of test sample and former after a short setting time, and thus production of several samples rapidly one after the other. The base (3) of the cylinder is a removable insert supported on a flange (5) projecting inwards from the cylinder wall (4) and having an outer dia. smaller than the inner cylinder dia. Alternatively the base may be fixed to the inner wall so that it is detached and removed from the top and/or bottom cylinder opening.</p> |
