Synthesis of high belite sulfoaluminate cement at low sintering temperatures (1225–1300 °C) using petroleum coke desulfurization residue (PCDR), fly ash (FA), carbide slag (CS), and bauxite (BX) was investigated. The thermal behavior, mechanical properties, heat of hydration, and hydration products of the developed binder were systematically studied. The results showed that the target C₄A₃S, β-C₂S, and C₄AF phases were successfully produced at 1225–1300 °C, and the industrial solid wastes can use up to 80%. The optimal sintering condition to obtain satisfactory clinker strength was 1300 °C, 45 min, and 10 °C/min, and the corresponding 1-d and 28-d strengths were 27.7 and 51.4 MPa. The early hydration products were mainly composed of AFt, AH₃, unhydrated C₄A₃S, C₂S, CaSO₄, and trace CH. The network structure formed by AFt interweaving was filled with AH₃ colloid, which was conducive to the improvement of cement strength. Furthermore, the cumulative heat release of the developed cement (191 J/g) in 3-d was lower than that of the sulphoaluminate cement (SAC) (198 J/g), effectively alleviating the rapid setting as compared to SAC and broadening its application range.

研究了使用石油焦脱硫残渣 (PCDR)、粉煤灰 (FA)、电石渣 (CS) 和铝土矿 (BX) 在低烧结温度 (1225–1300 °C) 下合成高贝利特硫铝酸盐水泥。系统地研究了开发的粘合剂的热行为、力学性能、水化热和水化产物。结果表明，目标 C ₄ A ₃ S、β-C ₂ S 和 C ₄AF相在1225-1300°C下成功生产，工业固体废物可利用率高达80%。获得满意熟料强度的最佳烧结条件为 1300 ℃、45 min 和 10 ℃/min，相应的 1-d 和 28-d 强度分别为 27.7 和 51.4 MPa。早期水化产物主要由AFt、AH ₃、未水合C ₄ A ₃ S、C ₂ S、CaSO ₄和微量CH组成。_{AFt交织形成的网络结构被AH 3}填充胶体，有利于提高水泥强度。此外，开发的水泥（191 J/g）在 3 天的累积放热量低于硫铝酸盐水泥（SAC）（198 J/g），与 SAC 相比，有效缓解了快速凝结并扩大了其应用范围。
