Driven by the growing demand for lightweight materials in sustainable construction, the interfacial bonding mechanism between all-lightweight shale ceramsite concrete and rebar requires further investigation. Therefore, 57 central pullout tests were conducted to systematically evaluate the effects of concrete strength, rebar diameter, surface shapes, and yield strength on the bond behavior. The results revealed two failure modes, pullout and splitting failures, controlled by the ratio of concrete cover thickness to strength. Increased concrete strength significantly enhanced bond capacity, wit...
