Response of Fiber Reinforced Polymer Confined Concrete Exposed to Freeze and Freeze-Thaw Regimes
Publication: Journal of Composites for Construction
Volume 6, Issue 1
Abstract
Unidirectional carbon/vinylester composites and concrete cylinders wrapped with three layers of the same composite were exposed to −18°C (0°F) conditions both with and without prior saturation by moisture and to freeze-thaw cycling after saturation. All specimens show degradation in strength, with the maximum degradation being due to the saturated freeze-thaw condition caused by cyclic effects of absorption, subsequent crack-opening and fiber-matrix debonding. Analytical predictions, based on approximation of hygrothermomechanical response models for composites combined with a simple confinement model, are shown to correlate well with experimental data for most of the exposure conditions.
