vi Nonmetallic Coatings for Concrete Reinforcing Bars James R. Clifton, Hugh F. Beeghly, and Robert G. Mathey This work was undertaken to ascertain the feasibility of using organic coatings, especially epoxies, to protect the steel reinforcing bars embedded in concrete of bridge decks from rapid corrosion. 2.

Note that billet-steel bars must also meet the supple-m e n t a r y re q u i r ement S1 of ASTM A , “St a n d a rd Sp e c - Specifications for epoxy-coated reinforcing bars Epoxy-coated reinforcing bars should be fastened with nylon-, epoxy-, or plastic-coated tie wire or other acceptable materials.
1. Scope. This specification covers ASTM Specification A low-relaxation Grade and Grade seven-wire prestressing steel strand with protective fusion-bonded epoxy coating applied by the electrostatic deposition method or other method that will meet the coating requirements in Section 7. Epoxy-coated reinforcing steel bars have been used for corrosion prot ection in o bridge structures in the US, covering an area of o, m 2 Author: David Bruce Mcdonald. However, when epoxy-coated bars are to be used, it is appropriate to: use epoxy-coated reinforcing for both top and bottom mats of slabs, minimize damage to Author: David Bruce Mcdonald. ACI , Sec. At the time concrete is placed, reinforcement shall be free from mud, oil or other nonmetallic coatings that decrease bond. Epoxy coating of steel reinforcement in accordance with Standards referenced in [ACI Sections] .
ASTM D / DM - 01() Standard Specification for Fabrication and Jobsite Handling of Epoxy-Coated Steel Reinforcing Bars. Active Standard ASTM D / DM | Developed by Subcommittee: D Book of Standards Volume: This specification covers the fabrication and jobsite requirements for deformed and plain steel reinforcing bars with protective epoxy coating applied in accordance with Specification A This specification is applicable for orders in either inch-pound units (as Specification D) or SI units (as Specification DM). After placing, walking on coated steel reinforcing bars shall be minimized. The placement of mobile equipment shall be planned to avoid damage to the coated bars. NOTE 2—Research has shown that steel-headed vibrators cause damage to epoxy-coated reinforcing steel bars when used to consolidate concrete. For the technical evaluation (Volume I), a three phase experimental investigation was conducted considering a wide range of corrosion-resistant reinforcing materials. These materials included stainless steels, microcomposite steel, and coated steels considering a variety of metallic and nonmetallic : Robert J Frosch, Samuel Labi, Chungwook Sim.
