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 ... -
Behaviour of Post-Tensioned Slab Bridges with FRP Reinforcement under Monotonic and Fatigue Loading
(University of Waterloo, 2013-07-02)The introduction of fibre-reinforced polymers (FRPs) to the field of civil engineering has led to numerous research efforts focusing on a wide range of applications where properties such as high strength, light weight or ... -
The durability of concrete using concrete plant wash water
(University of Waterloo, 2007-06-18)Hundreds of ready-mix concrete trucks are dispatched daily from ready-mix concrete plants. On average, a concrete truck has a carrying capacity ranging from 7 to 9 cubic metres of concrete, requiring about 1500 litres of ... -
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 ... -
Evaluation of Recycled Concrete Aggregate Performance in Structural Concrete
(University of Waterloo, 2012-05-18)Sustainable resource management and development have been at the forefront of important issues concerning the construction industry for the past several years. Specifically, the use of sustainable building materials and ... -
Experimental Investigation of the Shear Behaviour of Slender Concrete Beams Reinforced with GFRP
(University of Waterloo, 2019-09-19)Glass fibre-reinforced polymers (GFRP) are being used as longitudinal and shear reinforcement in specialized concrete applications. GFRP products are designed as direct replacements for conventional steel reinforcement and ... -
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 ... -
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 ... -
Prediction of the static modulus of elasticity in concrete cylinders using resonant tests
(University of Waterloo, 2019-10-15)Concrete is widely used in construction nowadays, and it is crucial that its behaviour conforms to the original design. In every construction site, standard concrete cylinders are cast for quality control. Concrete cylinders ... -
Punching Shear Retrofit Method Using Shear Bolts for Reinforced Concrete Slabs under Seismic Loading
(University of Waterloo, 2008-04-10)Reinforced concrete slab-column structures are widely used because of their practicality. However, this type of structures can be subject to punching-shear failure in the slab-column connections. Without shear reinforcement, ... -
Quality Assessment of Composite Materials using Ultrasonic Non-Destructive Testing Methods
(University of Waterloo, 2020-09-17)Non-destructive ultrasonic evaluation (NDE) is commonly used for assessment of civil infrastructure and characterization of construction materials. It is an efficient technique that could save millions of dollars with ...
