EXPERIMENTAL STUDY ON BOND BEHAVIOR OF GFRP REBARS AND RUBBERIZED CONCRETE

Abstract

Abstract: Based on the pull-out tests of 15 groups specimens according to CSA standard, the influence of the diameter of GFRP rebars,the incorporation rate of rubber and cubic compressive strength on bond behavior of GFRP rebars and rubberized concrete were studied. The test results show that the failure mode of mostly specimens are pull-out failure; the diameter of GFRP rebars,the incorporation rate of rubber and cubic compressive strength all have influences on the bond behavior of GFRP-rubberized concrete, and the bond performance decreases with the increase of the diameter of GFRP rebars and the incorporation rate of rubber, and increase with the cubic compressive strength of the increase of GFRP-rubberized concrete.

Key words: GFRP rebars, rubberized concrete, pull-out test, bond behavior
