If it dries in two or three hours and you can rub it with your hands, then it means it not works; either you did not sprinkle water, or the water retention rate of the mortar itself is not reasonable since typically the mortar is still wet after two or three hours on the wall.
The upper wall will definitely crack if the bulk density is too heavy. This is because the additives need to be appropriately adjusted. The additive manufacturer should compound the 0.5 additives. In addition to modifying the additives, you must also adjust the gradation. The quantity of...
You are right. I have encountered it many times. For the first time, I thought it was due to product quality, and I lost much money. Later, I discovered that my product did not cause this problem, so I recommend leveling putty for the bottom layer. It is a thin layer of the anti-crack followed...
We have encountered this situation. There are air bubbles on plastered concrete walls, but there are no bubbles on block or brick walls. The main reason is that the concrete walls have many pores and are airtight. The gas has to discharge outside so that plum up the mortar. It can optimize from...
There is a bit more powder, and the amount of cellulose ether is also a little more. Simply relying on a cellulose ether is not very good for construction. You can add an appropriate amount of air-entraining agents and other materials to improve the construction.
You don’t need to add additives. You can observe at the site. It will not affect the construction in winter. Your sand configuration is okay, and the quality is controllable. Don’t worry too much about individual data.
Bleeding should first consider three aspects:
1. Too many admixtures are added;
2. Added too much water;
3. The cellulose ether was added too little.
I saw that you wrote several formulas, but I needed to see data on fluidity. Is it because the bleeding was not measured? You must adjust the...
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...
