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;
 
Is it a decorative mortar formula? Blistering is generally a problem with cellulose ether. Try another variety.
 
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.
 
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.
 
What recipe is this? Isn't the tile adhesive a bit less cementitious material and cellulose ether?
 
Both water-reducing agents and cellulose have the effect of entrained air, excluding them one by one.
