(57) A method and system for forming a post-tensioned concrete slab using a post-tensioning concrete anchor. The system may comprise a connector anchor including a bore that includes a first frustoconical portion, and the connector anchor may be adapted to bear on the post-tensioning concrete anchor. The system may also comprise a coupler comprising a connector and a coupler body that includes a second frustoconical portion that is oriented oppositely to the first frustoconical portion. The connector may have a bore therethrough and may be configured to receive the coupler body and to engage the connector anchor. A pocket-forming cap may releasably engage the post-tensioning concrete anchor; the pocket-forming cap may include a frustoconical wall, a gripping head, and a connector-receiv­ing portion. The method may include using the system to form a second concrete section adjacent to a first concrete section before stressing the first concrete section.
