ABSTRACT OF THE INVENTION In processes for the production of a formwork assembly for casting concrete structures, side wall portions of the assembly are interconnected by connecting members which are produced by applying mortar, with the use of a bonding agent, to the inward side of the wall portion in openings in a template. A bell-shaped or disc-shaped casting mould filled with moist concrete is then turned over on to the mortar, being located in the correct position by the openings in the template. The respective halves of a formwork assembly produced in that way may be stacked with the interposition of thin plates and can be subsequently joined, for example by adhesive means. Modified forms of the process use dumbbell-like connecting members produced by means of axially divided mould portions, optionally with interposed separator between the co-operating portions.
