Abstract: The invention provides apparatus and method for forming concrete blocks, panels and the like with a reduced number of parts and production operations. The apparatus and method of this invention is contemplated for use at a concrete-mixing plant having the usual components such as mixers, hoists, cranes, and other transport facilities available at most modern mixing plants. The apparatus of the invention includes a pallet having a generally flat upper surface. In addition, there is provided a generally rectangular mold frame having four integral and generally vertical upstanding sides. The frame is generally open on the top and bottom and is dimensioned for matably mounting on the pallet. Cavity-shaping means are mounted within the frame and above the pallet for shaping block-forming molding cavities which are arranged for receiving concrete aggregate thereinto, whereby blocks may be formed by the deposition of the aggregate thereinto.
