Abstract: AFTER BEING PREHEATED OR BY USING THE RETAINING HEAT DEVELOPED DURING CURING, THE CONCRETE BLOCK IS PUT ON A LAMINATE COMPRISING A PLASTIC OR PAPER BASE, WHICH HAS PREDETERMINED RELEASE CHARACTERISTICS AND HAS BEEN PRECOATED RESPECTIVELY WITH (1) A PLASTIC RESIN, WITH OR WITHOUT (2) A DECORATIVE PLASTIC LAYER AND FINALLY (3) A HEATREACTIVE LAYER OF PLASTIC ADHESIVE WHICH SECURES THE LAMINATE TO THE BLOCK. THE INNER SURFACE OF THE RELEASE PLATE TO WHICH THE PLASTIC RESIN WAS AFFIXED WILL PERMIT REMOVAL OF THE RELEASE PAPER, THE PLASTIC LAYERS STAY ON THE BLOCK-FACE. THE RELEASE PLATE MAY BE LEFT ON AS A PROTECTIVE COVER DURING SHIPPING AND UNTIL AFTER THE BLOCK HAS BEEN LAID UP IN THE WALL.
