Concrete structures are increasingly reinforced by glass fiber-reinforced polymer (GFRP) rebar for its superior durability over steel rebar. Shotcrete is a low-cost and rapid method of concrete placement by high-velocity projection of concrete, enabling efficient construction of long-lasting GFRP-reinforced structures. The bond strength of GFRP rebar to concrete is a critical design consideration, and the bond of GFRP rebar to shotcrete has not been previously studied. This study outlines the testing of 12 notched beam bond test specimens that varied bar diameter (16 or 22 mm), bar surface profile (ribbed or sand-coated), and cover (19, 38, or 51 mm). Specimens were cast using either wet-mix shotcrete or pouring the same concrete mix. Beams were tested in four-point bending. Ten beams failed with splitting bond failures. Two beams had pullout bond failures at significantly lower loads than the splitting failures due to large voids in the shotcrete surrounding the GFRP bars of these beams. On average, bond strength was 8% lower in shotcrete compared to poured concrete due to small voids in the shotcrete. A greater proportion of ribbed rebar beams had voids than sand-coated rebar beams, leading to reduced bond strength of ribbed rebar in shotcrete. Shotcrete beams without voids had an equivalent bond to poured concrete. Ribbed rebar had lower bond strength than sand-coated rebar by an average of 17% when no voids were present. Smaller diameter rebars had higher bond strength, and increasing concrete cover increased bond strength.
