Effect of Thermal-Humid Media on Durability of CFRP-Wrapped Reinforced Concrete Columns
Abstract The objective of this study was to evaluate the effect of artificial aggressive conditions on durability of reinforced concrete (RC) columns wrapped with CFRP. Three groups of RC columns (150 × 300 mm) were casted and cured in same condition. They were, subsequently, exposed to three accelerated corrosion conditions, wrapped with one CFRP sheet, and then subjected to further post-repair corrosion. Artificial aggressive conditions were created by using mixed chloride and sulfate solutions, environmental cycling and temperature - humidity chamber. Initially, CFRP sheet worked as a protection barrier. It prevented aggressive agents (Cl− and ) from penetrating into concrete layer and declined possibility of corrosion of reinforcing steel. Nevertheless, anti-corrosion performance of CFRP sheet decreased sharply under the impact of high thermal condition. Eventually, the results revealed the anti-corrosion performance of CFRP-wrapped RC columns depend on the remaining content of harmful factors in concrete layer before being wrapped.
