Smooth -Formed Finished Concrete: Form -facing panels that provide continuous, true, <br />and smooth concrete surfaces. Furnish in largest practicable sizes to minimize number <br />of joints. <br />1. Plywood, metal, or other approved panel materials. <br />B. Rough -Formed Finished Concrete: Plywood, lumber, metal, or another approved <br />material. Provide lumber dressed on at least two edges and one side for tight fit. <br />C. Void Forms: Biodegradable paper surface, treated for moisture resistance, structurally <br />sufficient to support weight of plastic concrete and other superimposed loads. <br />D. Chamfer Strips: Wood, metal, PVC, or rubber strips, 3/4 by 3/4 inch, minimum. <br />E. Form -Release Agent: Commercially formulated form -release agent that does not bond <br />with, stain, or adversely affect concrete surfaces and does not impair subsequent <br />treatments of concrete surfaces. <br />1. Formulate form -release agent with rust inhibitor for steel form -facing materials. <br />F. Form Ties: Factory -fabricated, removable or snap -off glass -fiber -reinforced plastic or, <br />metal form ties designed to resist lateral pressure of fresh concrete on forms and to <br />prevent spalling of concrete on removal. <br />1. Furnish units that leave no corrodible metal closer than 1 inch to the plane of <br />exposed concrete surface. <br />2. Furnish ties that, when removed, leave holes no larger than 1 inch in diameter in <br />concrete surface. <br />3. Furnish ties with integral water -barrier plates to walls indicated to receive <br />dampproofing or waterproofing. <br />2.3 STEEL REINFORCEMENT <br />A. Recycled Content of Steel Products: Postconsumer recycled content plus one-half of <br />preconsumer recycled content not less than 60 percent. <br />B.
