Water retention of cellulose ether in mortar

Water retention is the most important feature of cellulose ether in building materials. Keeping enough moisture in mortar can be satisfied with work-ability over a long time range. Water plays a lubricating and stirring role in the inorganic composition. The addition of a small amount of cellulose ether can keep enough water in the mortar for a long time to promote continuous hydration of cement and improve mortar and substrate adhesion, due to the water retention effect of cellulose ether.

What does the water retention of mortar depend on, then determined the dosage of cellulose ether in mortar?

1. Cellulose ether content

2. Water absorption of substrate

3. Component of mortar

4. The thickness of the mortar layer

5. Water requirement for mortar

6.Setting time of the adhesive
