Abstract

To address the high cost and energy consumption issues associated with traditional cement-based materials, and in response to the national policies of carbon peak and carbon neutrality. This study utilizes bulk solid waste to prepare a fully solid waste paste filling materials. Materials such as fly ash, slag, steel slag, and desulfurized gypsum were used. Single-factor experiments and orthogonal experiments were conducted to optimize the mix ratio. The results indicated that after mix ratio optimization, the filling materials samples achieved compressive strengths of 0.866,2.489 and 5.612 MPa at 3days,7days and 28days, respectively, with a fluidity of 220 mm and a bleeding rate of 2%, meeting the specification requirements for strength and fluidity in mine paste filling. The results of the study provide a reference for field operations and cost reduction and low carbon reduction for field operations and cost reduction and low carbon emission reduction.
