Abstract: Retarding cement refers to a type of cement whose setting time is prolonged by adding retarders. This paper summarizes the definition, characteristics, and development history of retarding cement, and explores its specific production processes, including raw material composition and preparation, batching control, calcination and grinding, and addition of retarders. In response to the application challenges of retarding cement in high-grade highways, bridges, tunnels, high-temperature construction, and long-distance transportation, specific solutions such as optimizing material ratio design, enhancing environmental adaptability, and using high-strength materials are proposed. Practical applications have shown that the use of retarding cement can effectively extend the setting time of concrete, improve its workability and durability, ensure continuous construction without affecting later performance, and has broad market prospects.
