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 ... -
The Effect of De-icing Salts on the Chemistry of the Pore Solution in Cement Pastes and Their Influence on Rebar Corrosion
(University of Waterloo, 2020-01-15)Anti-icing and de-icing salts are an important tool used to increase traction and prevent the formation of black ice. Municipalities may choose to use any of a variety of salts including NaCl, CaCl2 and MgCl2. While all ... -
Effect of Forming Temperature and Sheet Temper on the Brazing Characteristics of Aluminum Alloy Sheet
(University of Waterloo, 2018-09-20)Automotive heat exchangers are fabricated by forming and brazing of multi-layered aluminum (Al) alloy sheets. The Al brazing sheets are comprised of two alloy layers: an AA3xxx core, which provides strength to the assembly, ... -
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 effects of curing- and service- conditions on durability of reinforced concrete structures
(University of Waterloo, 2020-06-01)Reinforced structural concrete is a critical building block of our civil infrastructure, especially our roads and bridges. As the transportation network grows, and our current infrastructure continues to age, the social ... -
Evaluation of Early In-Place Concrete Performance Based on Test Results of Cores and Cylinders
(University of Waterloo, 2018-08-21)The evaluation of in-place concrete performance, relating to its mechanical properties, continues to remain a challenge for engineers and researchers, but is essential for determining the safety of a structure and from the ... -
Evaluation of the Behaviour of Continuously Galvanized Rebar
(University of Waterloo, 2016-09-28)De-icing/anti-icing salts used during the winter season are the major culprit in limiting the durability of reinforced concrete structures. The salts induce corrosion of rebar, by penetrating the concrete and breaking down ... -
Influence of alloying elements, testing solution and surface roughness on corrosion behaviour of stainless steel reinforcing bars
(University of Waterloo, 2020-01-10)The province of Ontario has moved from applying rock salt crystals, predominantly impure sodium chloride, to locally available anti-icing brine solutions with chloride amounts as high as 21%. At the same time, the specified ... -
Investigating the Corrosion Behaviour of Carbon Black Steel Rebar in Ordinary and Limestone Cements With and Without Blast Furnace Slag
(University of Waterloo, 2022-09-30)Over the years, strange climate patterns have evolved over the globe, raising flags for concerns on the effects of global warming. Cement production contributes to 8% of the global carbon dioxide emissions. Without regards ... -
Investigation of Parameters Effecting Concrete Core Performance for Quality Control and Assurance
(University of Waterloo, 2019-04-23)The ever-evolving concrete construction industry has required stronger concrete, faster turnarounds, and better durability. To achieve this, the concrete mixtures have changed drastically, including a large amount of ...
