The Adaption of a Rapid Screening Test to Rank the Corrosion Behaviour of Stainless Steel Reinforcing Bars in Concrete
(University of Waterloo, 2018-08-21)The costs associated with aging reinforced concrete infrastructure in Ontario continue to rise as highway infrastructure, such as bridges, continuously deteriorate. The use of de-icing salts on these bridges in the winter ... -
Bond Behaviour of Corroded and CFRP Repaired RC Beams Subjected to Monotonic and Repeated Loading
(University of Waterloo, 2012-09-27)All reinforced concrete (RC) design theories are based on the assumption that concrete exhibits a perfect bond with the steel reinforcement. The bond between steel and concrete is essential to the transfer of the load ... -
Corrosion of reinforcing steel in loaded cracked concretes exposed to de-icing salts
(University of Waterloo, 2003)The corrosion of the reinforcing steel in concrete by de-icing salts is one of the major issues concerning the durability of reinforced concrete. Different methods have been used to protect the reinforcing steel, but ... -
Effect of Post-Rolling Surface Condition on the Corrosion Performance of UNS 32205 Stainless Steel Rebar
(University of Waterloo, 2022-04-29)During the winter season, ice accumulation on roads and sidewalks is a major problem and poses a hazard to road users. The most common method of addressing this issue is by applying de-icing salts or spraying a brine ... -
The Effect of Selected Coagulants on Chloride-to-Sulfate Mass Ratio for Lead Control and on Organics Removal in Two Source Waters
(University of Waterloo, 2009-01-22)Lead is a known toxin, with the ability to accumulate in the human body from as early as fetal development. Lead exposure is known to cause a myriad of health effects which are more prominent among children. Health effects ... -
The Effect of Surface and Loading Conditions on the Corrosion Performance of Stainless Steel Rebar
(University of Waterloo, 2009-01-22)Deterioration of reinforced concrete structures due primarily to chloride induced corrosion of plain carbon-steel reinforcement is a widespread problem, particularly in areas close to marine environments and where de-icing ... -
Effects of Surface Condition on the Corrosion Performance of Stainless Steel Rebar
(University of Waterloo, 2009-01-23)Corrosion of carbon (black) steel reinforcing bars (rebar) is the major cause of damage and deterioration of reinforced concrete structures in maritime regions and in climates where de-icing salts are used. The cause of ... -
Flexural Fatigue Behaviour of Corroded Pretensioned Beams and Their Repair Using Carbon Fibre Reinforced Polymer Sheets
(University of Waterloo, 2015-09-24)The study presented in this thesis investigated the flexural fatigue behaviour of non-corroded and corroded pretensioned beams and examined the use of externally bonded Carbon Fibre Reinforcement Polymer (CFRP) sheets as ... -
The Influence of Loading on the Corrosion of Steel in Cracked Ordinary Portland Cement and High Performance Concretes
(University of Waterloo, 2007-12-20)Most studies that have examined chloride-induced corrosion of steel in concrete have focused on sound concrete. However, reinforced concrete is seldom uncracked and very few studies have investigated the influence of cracked ... -
Predicting and Prolonging the Service Life of Weathering Steel Highway Structures
(University of Waterloo, 2009-08-25)Weathering steel is a high-strength, low-alloy steel which has been proven to provide a significantly higher corrosion resistance than regular carbon steel. This corrosion resistance is a product of the small amounts of ... -
The study of corrosion behaviour of Al, Cu and Zn in some commercial beverages by chemical and electrochemical
(University of Waterloo, 2012-08-29)The corrosion behaviour of pure copper, zinc and aluminum in selected commercial beverages was studied. Experiments were also conducted in the presence of citric and phosphoric acid to investigate their role in the corrosion ... -
Three-Dimensional CT Imaging and Microstructural Mechanical Modeling of Corrosion and Freeze-Thaw Damage of Concrete
(University of Waterloo, 2022-10-17)Corrosion and freeze-thaw can cause detrimental damage to concrete structures. Understanding concrete damage mechanisms at the micro-level can play an essential role in implementing effective preventive measures and efficient ...
