This study utilized carbide slag, steel slag, desulfurization gypsum, and fly ash as primary raw materials, with bauxite as the corrective material, to synthesize high belite ferroaluminate cement (HBFAC). A comprehensive analysis including thermogravimetric analysis (TGA), burnability analysis, X-ray diffraction (XRD) analysis, heat of hydration analysis, scanning electron microscopy (SEM), and mechanical property tests was conducted to systematically investigate the sintering performance and hydration behavior of solid waste-based HBFAC clinker with varying belite content. The results show that the mineral formation temperature range of solid waste-based HBFAC clinker is between 1 220 ℃ and 1 340 ℃, with an optimal calcination temperature of 1 300 ℃, which is 25 ℃ to 100 ℃ lower than that of conventional sulfoaluminate cement (SAC) clinker. The optimal holding time is 30 min. Under optimal calcination conditions, solid waste-based HBFAC clinker exhibits well-developed and uniformly distributed crystals, with a setting time delayed by approximately 20~30 min compared to SAC. The solid waste-based HBFAC exhibits characteristics of rapid setting and hardening, early high strength, sustained strength growth at later stages, and low heat of hydration. Its compressive strength is superior to that of SAC and ordinary Portland cement (OPC). The main hydration products include ettringite (AFt), monosulfate (AFm), aluminum hydroxide gel (AH3), and hydrated calcium aluminosilicate (C-A-S-H). Compared to tetracalcium aluminate sulfate (C4A3), dicalcium silicate (C2S) hydrates more slowly, contributing to the continued strength development of HBFAC in the later stage.
