Form Joint Tape: Compressible foam tape; pressure sensItive; AAMA 800, <br />"Specification 810.1, Expanded Cellular Glazing Tape"; minimum 1/4 inch (6 mm) thick. <br /> <br />G. Form Ties: Factory-fabricated, [glass-fiher-reinforced ptastic] [internally disconnecting] <br />[or] [removahle] ties designed to resist lateral pressure of fresh concrete on forms and to <br />prevent spalling of concrete on removal. <br /> <br />2.2 STEEL REINFORCEMENT AND ACCESSORIES <br /> <br />A. General: Comply with Division 3 Section "Cast-in-Place Concrete" for steel reinforcement and <br />other requirements for reinforcement accessories. <br /> <br />B.
