Reference number : GC-2017-Q2-04323, amendment number : , agreement type : G, recipient legal name : El-Hacha, Raafat (University of Calgary), recipient country : CA, recipient province : nan, recipient city : Alberta, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : In Canada, bridges are exposed to harsh weather conditions. Such conditions result not only in deterioration of_x000D_
the concrete but mainly lead to corrosion of the steel rebar. Deterioration of aging bridge structures represents a_x000D_
growing issue. Significant part of the issue is due to corrosion of the internal reinforcement. In Canadian_x000D_
environment, the rate of corrosion of the internal reinforcement in bridge structures is a function of several_x000D_
parameters such as temperature, i.e., cycles of freezing and thawing, level of humidity and direct exposure to_x000D_
water, presence of de-icing salts, sustained and repetitive loads, and time. Due these factors, concrete loses its_x000D_
ability to protect the internal reinforcement. Unprotected reinforcement starts to corrode sooner than_x000D_
anticipated and, therefore, reduces the bridge service life. To avoid shortening of the service life, and safe cost_x000D_
of maintenance, several types of advanced corrosion resistant reinforcing materials have been developed._x000D_
In this research, performance and durability testing is proposed on several types of corrosion resistant_x000D_
reinforcing rebars including Fibre Reinforced Polymer (FRP) (Glass FRP, Carbon FRP and Basalt FRP),_x000D_
Martensitic Micro-composite Formable Steel (MMFX), and Stainless steel, in addition to the conventional_x000D_
uncoated steel for comparison purposes. The reinforcing bars will be embedded in concrete specimens_x000D_
representing a bridge parapet. These reinforced concrete specimens will be exposed to severe weather_x000D_
conditions including spraying water and cycles of freezing and thawing then tested for ultimate capacity after_x000D_
the exposure. The study will evaluate material performance in terms of strength, durability, section loss of the_x000D_
rebar, ductility, and cracking patterns to not only establish reference guidelines for the industry but mainly_x000D_
broaden the fundamental knowledge about the behavioral patterns of selected materials in harsh environments._x000D_
It is expected that the different types of rebars will influence the response of the concrete beams when loaded._x000D_
As an outcome of the study, a report will be prepared summarizing how the application of the selected_x000D_
materials can extend the service life and reduce the maintenance cost of structures exposed to harsh weather., program purpose french : In Canada, bridges are exposed to harsh weather conditions. Such conditions result not only in deterioration of_x000D_
