Nine push-out test specimens were made and experimented to study the bond-slip behavior between steel section and geopolymer concrete. The influences of four factors such as compressive strength of geopolymer concrete, concrete cover thickness, embedded length of steel section and stirrup ratio on the load-slip curves, failure modes and bond-slip properties of the steel reinforced geopolymer concrete specimens were studied. The results show that the load-slip curves of different specimens have the same development tendency and can be divided into four stages: no slipping stage, load increasing stage, load declining stage and horizontal residual stage. The failure modes of specimens are bond splitting failure, cracks originate from the flange of the steel section at loading end and develop to the free end. As the compressive strength of geopolymer concrete, concrete cover thickness and stirrup ratio increase, the values of characteristic bond strength of specimens present a tendency towards growth. Unlike the steel reinforced concrete with ordinary cement, the values of characteristic bond strength of the specimens increase with the increase of embedded length of steel section. According to the test results, the calculation formulas of the characteristic bond strength are established, and the constitutive model of the steel reinforced geopolymer concrete is proposed. The bond-slip curves calculated by the model agree well with the experimental curves of steel reinforced geopolymer concrete specimens.
