Experimental research on interlaminal shear strength of GFRP bridge decks under simulated concrete environment XUE Weichen a , FU Kaib College of Civil Engineering, Tongji University, Shanghai, 200092, China axuewc@tongji.edu.cn, beric_fk@sohu.com Keywords: Simulated concrete environment; GFRP bridge deck; Interlaminal shear strength; SEM analysis Abstract.
According to the ACI 440.3R-04([6]), GFRP bridge deck samples were immersed in 60℃ of the simulated concrete environment for 92d (Corresponds to the natural environment 25 years) ([7] [8]), the mechanical behavior of GFRP bridge decks was evaluated by focusing on effects of corrosion time on the interlaminal shear strength. 1 Materials and Test Methods In this paper, GFRP bridge decks made up of E-glass fibers and vinyl ester resin were selected due to their wide applications in civil engineering.
