Freeze-thaw cycle is a major problem for the extended service life of a concrete structure in Canada. Variable weather and changed climatic condition is worsening the situation. This paper focuses on the effects of freeze-thaw cycles in concrete structures along with different loading conditions on pavements, sidewalks, bridges, roofs and other exposed structures. The study area considered here is the Okanagan Valley in British Columbia, Canada. Statistics indicate interesting results in terms of freezing-thawing cycle pattern in the winter season. Different types of concrete mix design have been considered and their durability against freeze-thaw cycles has been studied. Finally, a flow chart has been presented in predicting the susceptibility of freeze-thaw scenarios in terms of different cycles of freeze-thaw, varying loading conditions, and concrete type. In this paper the factors that affect the susceptibility of concrete due to freeze-thaw cycling is discussed. This paper focuses on concrete in mild continental Canadian regions in combination with factors including: (1) the concrete type, (2) application, (3) presence of salts, and (4) the type of loading. The flow chart has been assembled for the purpose of referencing and predicting the susceptibility of concrete designs to freeze-thaw degradation.
