Abstract: To actively promote China's dual carbon goals and the resource utilization of industrial solid waste, an all-solid-wastebinder was prepared using calcium carbide residue (CCR), basic oxygen furnace slag (BOFS), and ground granulated blast furnace slag (GGBS). Through laboratory experiments, the influence of CCR content and mass ratio of BOFS/GGBS on the workability and mechanical performance of the binder was systematically studied, and the phase composition, microscopic morphology, infrared absorption properties, and hydration mechanism were analyzed. The results indicate that when CCR amount is constant, with the increase of the mass ratio of BOFS/GGBS, the initial setting time of the paste increases, the flowability and bleeding rate increase, and the stone rate decreases. When the mass ratio of BOFS/GGBS is constant, with the increase of CCR amount, the initial setting time of the paste shortens, the flowability and bleeding rate decrease, and the stone rate increases. There is an optimal CCR content in the all-solid-waste cementitious system, and there is a synergistic effect between BOFS and GGBS during hydration. When CCR content is 20% and the mass ratio of BOFS/GGBS is 2∶8, the compressive strengths at 3 days, 7 days, and 28 days reach the maximum of 8.5 MPa, 16 MPa, and 32.1 MPa, respectively. CCR, BOFS, and GGBS can complement each other during hydration reaction;the rapid hydration of Ca(OH)2 in CCR provides Ca2+ and OH-, creating an alkaline environment for the formation of C-S-H gel, which fills pores, resulting in a denser structure and improved mechanical performance.
