ABSTRACT:
An electrically heated mold for making test specimens of concrete. The mold has two substantially identical mold halves pivotally mounted to each other and electric heating units selectively operated in response to the temperature variations in the concrete of the main structure. Each mold half has a heat transferring wall member which has a mold surface and an outer surface against which one of the heating units is placed. The mold is insulated and has a number of additional features designed to facilitate manufacture and operation of the mold as well as to increase its working life. These features include aligning members for aligning the halves of the mold as they close, two symmetrically positioned securing members that can be manipulated simultaneously by one person, an arrangement for preventing material from passing between the mold halves as they open in order to protect the insulation adjacent that area, an arrangement for initially prying the mold halves apart, and a stripping shoe for removing any molded test specimen that becomes stuck to one of the mold halves. The stripping shoe removes the molded test specimen without damaging the boundary areas and edges necessary for proper testing of the specimen.
