Tile adhesive does not dry thoroughly

425 350 90 mesh 600, stone powder 50, Wacker 6, 150,000 cellulose 2, starch ether 0.5, wood calcium carbonate 1, the sand is dolomite machine-made sand. I put the soaked bricks on for twelve hours, and the bricks can still be peeled off. The grout inside has not dried. Please give me some advice.
 
The feature of machine-made sand tends to accumulate some water, which results in more water being added. The water in the slurry is relatively large, and the water inside the bricks will be soaked, and the water will escape.

First, try not soaking the bricks in water, then add calcium formate. If that doesn't work, increase the amount of cellulose ether or add a water-reducing agent.
 
Is it because the water-soaked bricks absorb too much water? Will backwater after application affect the slurry?
 
There isn’t much cellulose either, so it shouldn’t be a problem with the formula.
 
Use low-viscosity cellulose either and try drying the bricks. If the slurry is still dry, you must check the cement. It is normal if the bricks can be broken off after 12 hours but abnormal if the slurry is not dry.
 
For regular tile adhesive, the fastest is check 24 hours strength. If within 12 hours unless add hard cement or you use it outdoors.
 
Use quick-hardening cement or add some calcium formate to accelerate the setting time.
It would be better if it is set in 12 hours.
 
Checking one by one, some cellulose either is compounded with retarder.

If all the final results are the same, change the cement, add R cement, or add calcium formate.
 
Use pure cellulose ether. If it is not pure, it may contain a retarder. The cellulose does not need to be so highly viscous. If there is no problem but cannot be dried, consider using cement with R or lower the cellulose ether. After all, it’s getting colder now, so you can consider adding calcium formate.
 
Add early strengthening agent, 6 kg, try it. In addition, if the anti-slip effect of cellulose either is acceptable, try removing the starch ether.
