摘要: Moisture exposure has been observed to be one of the degrading environmental agents which affect durability FRP-strengthened elements by changing constituent material or bond properties. This paper presents experimental investigation on effects moisture pull-off strength GFRP-strengthened brick specimens. The specimens have prepared following wet lay-up procedure and exposed constant level 100% R.H. at 23 C for eight weeks. degradation in performance investigated performing tests conditioned after four weeks exposure. reversibility also studied storing some laboratory conditions week conditioning before tests. Comparative analysis performed main results are presented discussed.
