Advantages
| |
| At low dosage, it can play a good retarding effect, and the setting time is controllable. | Suitable for natural and industrial by-product gypsum such as phosphogypsum and desulphurized gypsum, and compatible with various other additives; |
| |
| Good dispersion, easy to dissolve in water, easy to mix evenly, do not increase the process. | With the increase of retarder dosage, the setting time is relatively slow and average longer, and the setting time is easier to control. |
