EXPERIMENTAL RESEARCH ON LONG-TERM MECHANICAL BEHAVIOR OF GFRP BARS IN DIFFERENT ENVIRONMENTAL CONDITIONS

Abstract

Abstract: An around one-year experimental test of long-term mechanical behaviour of GFRP bars in different environments was carried out, including concrete environment, alkaline solution and natural UV radiation, respectively. This study is designed to verify the reliability of usual accelerated aging tests on GFRP bars and simulation of the actual time-dependent property of GFRP bars embedded in concrete. The experimental results showed that the degeneration in the mechanical property of the GFRP bars packaged in concrete and exposed to the natural environments was not so significant, while the property of the GFRP bars storing in the alkaline solution was degenerated by around 20%.

Key words: GFRP bars, environments, concrete, UV radiation, alkaline solution, degeneration
