An apparatus for assembling two cement board stay-in-place form panels for making concrete-filled walls that is cost-effective and forms a uniform precise composite wall construction. The assembly includes a coextensive corrugated spacer panel between the form panels for maintaining a uniform distance there between. The forms and spacer panels are secured in place with a notched tie rod that penetrates the spacer and both wall panels, this assembly allows for rapid form installation. The spacer panel has two embodiments, viz. i) a preformed rigid corrugated panel and ii) a flattened unassembled panel with precut fold lines that are folded at the building site and then secured with a dowel-rod bracing component. The apparatus preferably uses fiber-glass-reinforced cement board for the stay-in-place forms. The final composite wall construction typically is made up of 4 feet wide by 8 feet high by 6.5-inch thick composite wall sections. The form walls use standard 4 feet by 8 feet by half-inch thick concrete or cement bard. Assembly of composite wall form requires erecting the corrugated spacer panel first and then attaching two form panels to the spacer panel\s corrugations thereby forming a series of vertical compartments that are then filled with concrete or foam concrete with proper reinforcement.

A composite concrete-filled wall comprised of a concrete filler, a pair of exterior facing panels, at least one corrugated spacer panel between the pair of exterior facing panels and multiple tie rods with notches at their extrema for holding together and stabilizing the pair of exterior facing panels at a uniform distance apart in relation to the at least one spacer panel prior to pouring of the concrete filler, wherein the spacer panel is continuous and coextensive with the facing panels and the multiple tie rods are made of a clip shearable material, whereby the corrugated spacer panel and the pair of exterior facing panels form a series of hollow compartments into which the concrete filler is poured resulting in a uniform-dimensioned, non-bulging composite wall.
