Fusion-bonded epoxy-coated rebar (FBECR) was studied by casting in a poor quality concrete and subjecting the specimens to a cyclic wet/dry exposure (monthly) using either 3.5% NaCl or demineralised water over a period of 12 months. On-going measurements of half-cell potentials were made together...
This paper reports the influence of sulfate concentration on chloride-induced reinforcement corrosion in Portland cement concretes (with C 3 A varying from 3.6% to 9.65%). The concrete specimens were exposed to mixed chloride and sulfate solutions for a period of 1200 days. The chloride was fixed...
Oregon's coastal highway includes over 120 bridges, most of which are reinforced concrete bridges. Twelve are historic structures. Over 40,000 m 2 of bridge surface has been repaired and is protected from further corrosion damage using thermal-sprayed zinc anodes in impressed current and galvanic...
Current distribution from a surface mounted anode to steel reinforcement in atmospherically exposed concrete is modelled as a function of the condition of the steel, the resistivity of the concrete and anode-steel geometry. The boundary conditions at the steel have a significant effect on current...
The excellent corrosion resistance of steel in reinforced concrete is decreased in the presence of chloride ingress the carbonation of this cover. The use of inhibitors is one of several possible methods to protect rebar from corrosion. The most common practice is their addition together with the...
