Environment-friendly liquid accelerator and preparation method thereof

According to the environment-friendly liquid setting accelerator and the preparation method thereof, coordination between aluminum and hydroxyl can be promoted by introducing manganese ions, the setting accelerating performance and the early strength performance are improved, the environment-friendly liquid setting accelerator has good adaptability to different kinds of cement and has a good early strength effect, and in addition, the environment-friendly liquid setting accelerator is different from a traditional setting accelerator which is large in later strength loss and low in cost. The 28d compressive strength ratio of the cement is greater than 100%, the later strength of the cement is guaranteed, the cement contains substances such as alkali, chlorine and fluorine, the later strength of the concrete is not reduced without alkali, steel bars in the concrete are not corroded without chlorine, harmful substances such as HF are not generated without fluorine, the safety is high, and the storage time is pro
