ABSTRACT:
A mold for forming concrete having a bottom, a pair of side walls and a pair of end walls, all of plastic, and with the side walls and bottom being of integral one-piece construction and hinged together by living hinges defined by reduced thickness of the plastic panel. The ends walls are shaped with generally U-shaped channels dimensioned to lock onto the ends of the bottom and side walls whereby a watertight concrete mold is formed. The concrete mold is assembled by pivoting the side walls to an upright position relative to the bottom by means of the living hinges and the end walls are then secured to the bottom and side walls. The mold can be disassembled for removal of a formed concrete specimen by removal of the end walls and pivoting the side walls downwardly to a generally coplanar relation with the bottom to expose the test specimen for removal.
