Please correct the tile adhesive formula if there is any concern (we have higher temperatures in the south and it doesn’t snow in winter)

Formula is like below(unit:kg)

425 cement:350, calcium carbonate powder:50, 40~70 mesh sand:350, 70~140 mesh sand:250, Wacker 5044n:12, HPMC 4W:3,

starch ether:0.3, water reducing agent:0.3, Calcium Formate:0.3
 
Do not add water-reducing agents. The amount of calcium formate doesn't have much effect. It is best to differentiate between summer and winter. Calcium carbonate powder is recommended to add 25 as an additive mixture.
 
This formula is good, and the quality is guaranteed. Depending on the market, you can choose to add calcium formate or not, or you can make two formulas. For example, if in the south, your formula is okay, you can consider not adding calcium formate; if in the north and the construction is winter, then calcium formate still needs to be added with a significant amount. If too much calcium formate is added, it will quickly become alkaline in areas with high ambient temperatures.
 
It's a relatively responsible company, and the price is certainly not low. This is a good formula, but it needs much tweaking.

Adding 3 to 4 kilograms of calcium formate, an optional water-reducing agent and 0.3 to 0.4 kilograms of starch ether is recommended, depending on the mass. You'd better pay attention to the sand grading.

Ultimately, it’s better to do more experiment, and let the data speak for itself.
 
You need to add a few more calcium formate. The early strength effect is noticeable. In winter, the temperature is low, and the strength is slow, so add some calcium formate. As for summer, some people will add a little calcium formate to replace the redispersible polymer powder to reduce costs partially, and the strength is quite good.
 
Personally, I think you can add 0.5 kg of water reducing agent and 0.5 kg of starch ether. No need to add calcium formate.
 
I feel that since the amount of starch ether is too small, it is best to use 200,000 viscosity for mortar products.
