1. Special personnel must be responsible for the preparation of polymer mortar to ensure the mixing quality.
2. Turn the lid counterclockwise to open, and re-mix the binder with a stirrer or other tools to avoid separation of the binder. Stir moderately to avoid quality problems.
3. The mixing ratio of polymer mortar is: KL binder: 425# sulphoaluminate cement: sand (with 18 mesh bottom): = 1:1.88: 3.25 (weight ratio).
4. After weighing the amount of cement and sand in the bucket, pour it into the iron ash tank for mixing. After mixing evenly, add the binder according to the mixing ratio and stir. The mixing must be uniform to avoid segregation and porridge-like. Water can be added appropriately according to workability.
5. Water is used for concrete.
