[0002] Accelerator is an additive used in building materials such as concrete and mortar. Its main function is to accelerate its setting and hardening process. It is usually added to cement to shorten the setting time of concrete during construction and improve work efficiency, especially in low temperature environments. It can prevent the concrete from remaining moist for too long, resulting in failure to develop strength in time. The use of accelerator can help construction projects increase construction speed, especially in projects that require rapid prototyping, such as the production of prefabricated components, road repairs, etc.

[0003] The working principle of accelerators is to accelerate the hydration process of cement by changing the rate of cement hydration reaction, thereby accelerating coagulation and hardening.
