Moreover, due to less bond strength, more development length required, leading to more cost. Epoxies have been used in painting reinforced steel for bridges and offshore = Non-epoxy coated = Epoxy coated times the development length. Iron left in the atmosphere corrodes very easily. Preferences of epoxy coated rebar. This is generally the bar used in bridges and department of transportation projects. Epoxy coated rebar is a viable option and I think overall, it will provide you with significant protection from corrosion based on much history and testing. In some cores, sufficient concrete was not available to collect the required sample. Rebar is found in every building you can imagine. 1" X 18" EPOXY SMOOTH. There is no explicit provision in the Code addressing a cover depth reduction over epoxy-coated reinforcement. Burke, D. F. 1994. coated bar. The use of epoxy-coated rebar is commonplace today for precast concrete applications in bridges and roadways, marine applications, parking structures, concrete repair and structures challenged with corrosion from deicing chemicals, continuous moisture exposure and/or salts. Pavements (highway, airport runway, etc.) Steel reinforcing bars, referred to as rebar, bring strength and stability to structures made of concrete and masonry. Epoxy Coated . In fact, well over 80,000 bridges have used epoxy coated rebar. We will use this information to improve the site. If the Epoxy-Coated Steel Reinforcing Bars (rebar) are to be exposed outdoors for more than 30 days, cover with a suitable opaque material that minimizes condensation. Store coated and uncoated bars separately. Corrosion is the transition of Iron to its Oxides and Hydroxides in the presence of oxygen and water. Used in high stress applications: higher carbon content provides increased vertical strength. The epoxy coating provides additional protection against corrosion. The contractor is a quarter of the way through the foundation's rebar, and now an internal debate amongst my colleagues is raging about whether they should be using epoxy-coated or not. Applications for epoxy coated steel reinforcing bars include: Bridges Epoxy-coated reinforcing steel (or rebar) is also known as fusion-bonded epoxy-coated rebar or FBECR. The concept of a barrier coating was successfully being used by the underground pipe industry, and, following suit, the NYSTA began coating rebar with epoxy by the early 1980s. Scroll right. We stock epoxy-coated rebar in conformance with ASTM A775 in sizes #3 through #11 and can supply up to #18 specific to a projects requirements. 128 Epoxy-coated bars can be used in structures with other reinforcing steel bars; however, 129 when using epoxy-coated reinforcing steel in decks it is recommended that all the deck 130 steel is coated as this will reduce the overall rate of corrosion if the coating is damaged. All cut ends had to be epoxied.

Epoxy coated rebar (ECR) is used the same way but is used in areas that have high corrosion, such as bridges, pavements, and marine structures. Epoxy-coated rebar resists corrosion from salt and water that penetrate concrete members, especially at seams and cracks. It has the same textile strength but is over a hundred to a thousand times more resistant to corrosion. This length is governed by the concrete strength and the yield strength of the rebar. Epoxy-Coated Rebar Condition and Properties. Figure 1 presents the percentage of rebar that had a chloride content in the surrounding concrete at or greater than a given level. Fabricating epoxy coated bars can be challenging in cold weather, (sometimes even in warm climates too), and causes some coatings to crack at the bend. In the construction industry, one of the biggest challenges that engineers face is reducing rebar corrosion. Follow required design requirements for ECR, as outlined in ACI 318. In the case of steel rebar in concrete, we see in 250.52(A)(3)(Information Note) that epoxy coated rebar and/or a vapor barrier can negate our ability to use the rebar as an electrode, however our mandate to bond the systems to form a common system still remains under 250.50.
