Steel reinforcing bars extracted from (A) PC and (B) AAS mortars, each exposed to 1 M NaOH solution containing 3.5% NaCl for 270 days [42]. Steel embedded in AAS mortars did not exhibit any corrosion.In response to a need for corrosion-resistant reinforcement replacing conventional corrosion-prone uncoated steel, aka black steel, several types of advanced materials have been developed and used in several industrial applications. Specific materials have been studied and tested independently or in small groups.DW Pfeifer's 14 research works with 263 citations and 4,216 reads, including: Corrosion-resistant reinforcing bars Findings of a 5-year FHWA Study

When it comes to purchasing stainless steel sheets, one of the most popular choices is 304 stainless steel. This versatile alloy offers excellent corrosion resistance, durability, and aesthetic appeal, making it ideal for a wide range of ap...Reinforcement corrosion in concrete structures, its monitoring and service life prediction – A review. Cem. Concr. Compos. (2003) ... (CFCSTs) are newly proposed for strengthening the corrosion resistance, ductility, and constructability of traditional RC structures. Their composite effectiveness and basic compressive, bending, and shear ...Exposure of reinforced concrete to chlorides is the major cause of premature corrosion of steel reinforcement, although corrosion can also occur in some circumstances in the absence of chlorides. For example, sufficient amounts of other substances such as other halides, chlorate, and hypochlorite can result in corrosion (Kerkhoff 2007; ACI 515.2R). Because corrosion of reinforcement can result in concrete cracking, staining, spalling and costly repairs, corrosion-resistant reinforcement often is the obvious choice for concrete structures exposed to high chloride levels. What isn't so clear-cut is the best type of rebar to use for a particular project. Epoxy-coated, galvanized, glass-fiber ...Development of corrosion resistance of reinforcement steel bars with nano-silver coatings. The aims of this study are to examine the effect of metallic coatings on …

... corrosion-resistant reinforcing steel. A new iron-alloy, containing nine percent chromium with the trade name MMFX II, was developed to be corrosion resistant.Intrinsic reinforcement is a reward-driven behavior that comes from within an individual. With intrinsic reinforcement, an individual continues with a behavior because they find it personally rewarding, not out of fear of punishment or for ...

Carbide-reinforced martensitic steels, known as high-speed steels (HSSs), have been used as tool materials in various industries because of their high hardness and wear resistance. Nonetheless ...In recent years, various corrosion resistant alloys and corrosion inhibitors with improved performance has been investigated. Various approaches, on the other hand, must be commercially feasible. Furthermore, new procedures for internal corrosion inhibitor coatings must be developed in the early phases without entirely replacing the pipelines. 5.4.Electrochemical potential mapping according to guideline B3 of DGZfP (German Society for Nondestructive Testing) is a recognized technique for the localization of corroding reinforcing steels. In reinforced concrete structures the measured potentials are not necessarily directly linked to the corrosion likelihood of the reinforcing steel. The …
