A large number of bubbles are generated when stirred as per the following formula. I don't know why. Here is it,
1. 250 kg of cement;

2. 300 kg of 50-100 mesh yellow sand;

3. 325 kg of 70-140 mesh yellow sand;

4. Heavy Calcium Carbonate 100 kg;

5. Redispersible Polymer powder 20 kg;

6. Cellulose ether 1 kg (100,000);

7.3mmpp fiber 1kg;

8. 1 kg of water-reducing agent;

Redispersible Polymer powder sometimes produces air bubbles.

 

[Scott Kaplan]

Not the Redispersible Polymer powder causes air bubbles, the water reducing agent causes it.

 

[Luis]

Is it a decorative mortar formula? Blistering is generally a problem with cellulose ether. Try another variety.

 

[Allen]

The air-entraining agents are water-reducing, Redispersible Polymer powder, and cellulose ether. Is your formula used to make tile adhesive?

If the amount of air bubbles is large, it may be caused by Redispersible Polymer powder.

 

[Cassie]

Such problems are likely to occur when polycarboxylate water reducing agents are used together with cellulose ethers, and antifoaming agents generally need help to solve them effectively.

 

[Alex]

What recipe is this? Isn't the tile adhesive a bit less cementitious material and cellulose ether?

 

[Ankur]

Both water-reducing agents and cellulose have the effect of entrained air, excluding them one by one.
