Boric Acid Corrosion of Concrete Rebar
Borated water leakage through spent fuel pools (SFPs) at pressurized water reactors is a concern because it could cause corrosion of reinforcement steel in the concrete structure and compromise the integrity of the structure. Because corrosion rate of carbon steel in concrete in the presence of boric acid is lacking in published literature and available data are equivocal on the effect of boric...
متن کاملCorrosion Behavior of Stainless Steel Clad Rebar
Stainless steel clad rebar (SCR) was investigated because it may become a cost-effective means of controlling corrosion in concrete under very aggressive environments. Sound SCR (316L cladding) resisted corrosion in saturated Ca(OH)2 solution (SCS) with up to 5 wt% chloride. Cladding breaks on SCR induced significant corrosion of exposed underlying CS in SCS with only 1 wt% chloride. A computer...
متن کاملOptical-Based Sensors for Monitoring Corrosion of Reinforcement Rebar via an Etched Cladding Bragg Grating
In this paper, we present the development and testing of an optical-based sensor for monitoring the corrosion of reinforcement rebar. The testing was carried out using an 80% etched-cladding Fibre Bragg grating sensor to monitor the production of corrosion waste in a localized region of the rebar. Progression of corrosion can be sensed by observing the reflected wavelength shift of the FBG sens...
متن کاملCorrosion Performance of Epoxy-coated Rebar in Florida Keys Bridges
Severe corrosion of epoxy coated rebar in the substructure of 5 major marine bridges in the Florida Keys was detected after only a few years of construction. Corrosion occurred underneath the coating and was preceded by loss of adherence between the steel and the coating. Damage surveys of the bridges, which were built around 1980, were conducted from 1986 to 2000. Corrosion resulted in delamin...
متن کاملBiomechanical assessment of three rebar tying techniques.
The National Institute for Occupational Safety and Health (NIOSH) conducted a study of ironworkers to evaluate their risk for developing back and hand injuries from hand-tying reinforcing steel bar and to investigate whether power tying tools can be an effective intervention for the prevention of work-related musculoskeletal disorders. A field investigation of biomechanical loading when using 3...
