ABSTRACT:
A plastic foam core concrete plank and the method of making same is described which employs foamed plastic core forming members positioned on an initial layer of concrete in a forming pallet and held translationally and vertically in position relative to the initial layer of concrete as a top layer of concrete is poured into position around and over the core members to complete the slab. The core members have a plurality of discontinuous recesses extending from one surface thereof which are exposed to the lower or initial layer to create voids in the slab for light construction and to decrease the thermal transmissions therethrough.
