Recently, in the practical field of civil engineering, the most popular bond material used for strengthening reinforced concrete structures is epoxy. The good adhesive effect of epoxy has been widely confirmed. However, its poor heat resistant property is also well known. Preceding works have studied the possibility of using a newly developed inorganic bond material, namely geoplymer, to replace epoxy. Including the strength of concrete cylinders confined by CFRP using geopoliner, as well as their heating resistant experiments. The results were encouraging.
In the present study, it is attempted to step forward. The effect of shear strengthening of reinforced concrete beams with FRP jacket by using geopolymer as bond material under room temperature was investigated. The parameters of the experiments included three different concrete strength, namely 140, 280, and 350 kgf/cm2, two kinds of FRP jacket material, namely CFRP and GFRP, and two different layers. The size of the reinforced concrete beam specimens is 15 cm x 20 cm x 150 cm. The results of the study show that the overall shear strengthening effect of the beams is not better than those of using epoxy, but it reveals that the common requirements of shear strengthening are indeed fulfilled.
