Recycled Concrete Aggregate: Influence of Aggregate Pre-Saturation and Curing Conditions on the Hardened Properties of Concrete
(University of Waterloo, 2014-05-13)
Recycled concrete aggregate (RCA) is a construction material, which is being used in the Canadian construction industry more frequently than it was in the past. The environmental benefits associated with RCA use, such as ...
Bond and Development Length in Concrete Beams with Exposed Reinforcement
(University of Waterloo, 2013-09-19)
Corrosion of steel reinforcement in Ontario bridges is causing severe soffit spalling in many situations. These spalled areas are often located within the lap splices and curtailment zones of the primary reinforcement. ...
Evaluating the Effects of Spalling on the Capacity of Reinforced Concrete Bridge Girders
(University of Waterloo, 2011-09-01)
Corrosion of the reinforcing steel is a primary deterioration mechanism for reinforced concrete bridges. Heavy use of de-icing salts is believed to be a major contributor in Ontario to severe girder soffit spalling in ...
Finite Element Modelling of GFRP Reinforced Concrete Beams
(University of Waterloo, 2015-04-29)
The numerical modelling of twelve concrete beams reinforced with glass fibre reinforced polymer (GFRP) longitudinal and transverse bars was performed by the author using the finite element analysis (FEA) software ABAQUS. ...
The Case for Stainless Steel Reinforcing Bars
(University of Waterloo, 2015-03-19)
As Canada’s ever expanding transportation network continues to age, the costs associated with rehabilitating and replacing structural elements, such as bridges, continues to grow. This rehabilitation is often required ...
Sample size eﬀect in ultrasonic testing of geomaterials - numerical and experimental study
(University of Waterloo, 2008-05-21)
Nondestructive evaluation of civil structures is of increasing interest to utility owners. Several methods exist to evaluate different properties of concrete, pavement, cemented sands and others. UPVM is the most commonly ...
