## 1 Introduction  
As the world's most widely used construction engineering material, cement has a considerable annual output worldwide due to its good hydraulic properties and workability, wide and low-cost raw material sources, and programmed production process. However, cement consumes a lot of energy and generates a lot of CO\({}_{2}\) in the production stages such as clinker grinding and limestone calcination. Production technology in the cement industry has also been evolving in recent years, with an increasing focus on sustainable, cost-efficient, and energy-efficient production to reduce energy consumption and greenhouse gas emissions [1, 2]. The mineral composition contained in sulphoaluminate cement (CSA) is mainly anhydrous calcium sulphoaluminate (C\({}_{4}\)A\({}_{3}\)S) and \(\beta\)-dicalcium silicate (\(\beta\)-C\({}_{2}\)S), which is calcined at a lower temperature, thereby reducing the CO\({}_{2}\) emissions caused by the combustion of the fuel. However, the high proportion of C\({}_{4}\)A\({}_{3}\)S in CSA can easily lead to problems such as excessive cement setting time and unstable strength growth at later ages [3, 4, 5, 6]. Therefore, by adjusting the ratio of \(\beta\)-C\({}_{2}\)S and C\({}_{4}\)A\({}_{3}\)S in SAC and increasing the content of \(\beta\)-C\({}_{2}\)S, the development of cement strength in the later stage is effectively guaranteed and the amount of alumina is reduced. It provides the conditions for the utilization of low-quality aluminum resources, forming high-belite sulphoaluminate cement (HBCSA) [5, 7, 8, 9, 10, 11, 12, 13, 14]. Compared with CSA cement, HBCSA cement has a lower calculation temperature (50-100 \({}^{\circ}\)C lower than that of CSA cement), consumes less energy in production, and emits 50-80% of the amount of CO\({}_{2}\) that traditional CSA cement emits [15]. It is of great significance to the cement industry's energy conservation, environmental protection, and sustainable development. Due to the fast hydration rate of CSA cement, in order to overcome the rapid setting of CSA and ensure the continuous hydration of \(\beta\)-C\({}_{2}\)S, it is usually necessary to use a retarder to delay the hydration rate of cement [16]. For example, the addition of organic retarders sodium gluconate, tartaric acid, and citric acid can delay the hydration of cement by inhibiting the precipitation or growth of ettringite, and sodium gluconate can slow down the hydration reaction more than tartaric acid. This shows that the interaction with cement hydration is stronger at the same test content, and the retardation effect of citric acid and sodium gluconate gradually weakens with the increase in temperature [16; 17; 18]. However, tartaric acid will reduce the strength of cement mortar at an early age, but it has little effect on the compressive strength in the long term [19]. Citric acid and sodium gluconate can significantly improve the early strength of CSA cement [16]. In addition, after adding inorganic retarder borax or boric acid, it will precipitate with Ca\({}^{2+}\) in the cement particles and adsorb on the cement surface, thereby forming a calcium-based borate layer, preventing the dissolution of ye'elimite [16; 17]. In addition, the special properties of rapid setting and high early strength of sulphoha-luminate cement result in poor working performance, which requires a water-reducing agent to improve [20; 21; 22; 23]. Therefore, the use of a superplasticizer can improve the fluidity of cement paste, and a retarder can prolong the setting time of the paste. Combining the two is beneficial to maintain good fluidity and workability of the cement paste [22], but the compatibility between the two remains to be studied. Some studies have shown that the initial fluidity of the cement paste will be reduced due to the competitive adsorption of superplasticizer \(\beta\)-naphthalenesulfic acid-based water-reducing agent (BNS), sulfamic acid-based water-reducing agent (AS), and citric acid after compounding [22; 23; 24].
