.../methodology/approach This paper presents a geopolymer adhesive that matches the performance requirements of CFRP adhesive, which is applied to pre-cracked beams reinforced with CFRP strips. Findings For specimens with varying structural properties, two failure modes, the CFRP-concrete interface...

...Jinliang Liu; Fangpu Yan Purpose In this paper, the effects of geopolymer adhesive, the number of CFRP layers and the width of pre-crack on the flexural performance of reinforced concrete beams strengthened with CFRP were studied, and the flexural capacity of strengthened beams was calculated...
