A concrete wall form having spaced-apart wall forms forming opposing surfaces that define a cavity for forming a concrete wall are provided with a plurality of improved lighter weight wall form ties that hold the walls in a desired relationship. The improved wall form tie includes an elongate strip of material having two opposite elongate edges and a fastening aperture defined at each of two opposite ends of the elongate strip for attachment of the wall tie to wall forms. A plurality of notches spaced-apart along each of the two opposite elongate edges of the strip between the fastening apertures facilitate proper placement and retention of reinforcing bars in a cavity defined between the concrete wall forms. Weight-reducing apertures defined within an area between adjacent notches provide recyclable scrap material and reduce the weight of the wall form tie, thereby reducing manufacturing and freight costs.
