QA About Galvanized Reinforcing SteelConcrete

Jun 06,2012 PDF Bond strength of HOT Dip galvanized reinforcement#0183;Galvanized rebar is making a comeback.Hot dip galvanizing (HDG) is a process for protecting steel from corrosion by completely cleaning the steel member and then immersing it in molten zinc.The molten zinc reacts with the steel surface to form stratified zinc-iron alloy layers which are metallurgically bonded to the steel.People also askDoes galvanized rebar cause concrete spalling?Does galvanized rebar cause concrete spalling?As corrosion continues,the pressure will eventually exceed the tensile strength of the concrete causing the concrete to crack and spall as shown in figures 1 and 2.The corrosion products of galvanized rebar are less dense and do not build up pressure to cause concrete spalling.Reference galvanizeit/uploads/publications/galvanized_rebar_vs_epoxy_rebar. results for this questionIs galvanized rebar stronger than black steel?Is galvanized rebar stronger than black steel?More recent studies have all shown that galvanized rebar bond strength is equal or higher than black steel bond strength.It cannot be denied that the bright,uniform and smooth appearance of a well-galvanized surface gives one the impression of much poorer adhesion than that of bare steel mill scaled or rust on the surface.Bond Strength of Galvanized RebarPRODUCT SUBMITTAL WIRE-BOND 1100 Triangular TieJoint Reinforcement) ACI / ASCE 530 (Building Code Requirements for Masonry Structures) Mill Galvanized coating ASTM A641/A641M (0.1 oz/ft) Hot-Dip Galvanized after fabrication ASTM A153/A153M-B2 (1.5 oz/ft) Wire (Stainless Steel) ASTM A580/ASTM 580M - AISI Type 304 (Type 316 available on special orders) Recycled Content:

Galvanized reinforcement in concrete has much better bond (or pull-out) strength than either black or epoxy coated reinforcement.Exceptional Life Cycle Cost When the costs and consequences of corrosion damage to a reinforced concrete structure are analyzed,the extra cost of galvanizing is a very small investment in long-term corrosion protection.HDG Rebar vs.Epoxy Coated Rebarthe bond strength of ribbed galvanized and black rebar. ACI Code requires the basic development length for ribbed epoxy-coated bars to be increased due to the loss of bond strength as a result of the epoxy coating.Fabricate After Coating HDG can and is often fabricated/bent after coating.Galvanized Reinforcement Recent Developments andApproaches to the design of galvanized reinforced concrete including bond strength and slip are discussed as well as general fabrication practices.Recent applications of galvanized reinforcement in large construction and infrastructure are presented.Results from a life-cycle cost and total present cost analysis of epoxy-coated,grade 316
