Does white cement have hardness when it is dry?
I believe many friends don't understand whether the white cement is hard when it is dry. Let's take a look at this problem!
This kind of cement will have a certain hardness when it is dry, but the hardness is not very high. Because white cement is a decorative material, it is usually used for jointing. Although its manufacturing technology is better, its strength and hardness are not high, so it is not suitable for wall use. In addition, white cement is afraid of water and cannot be used as waterproof material.
In the process of using cement, we should pay attention to moistureproof. Because once the cement is wet, its strength will be reduced, which will affect the firmness of the house after use.
When using cement, it must be placed in a cool and ventilated place, and it can't be exposed to the sun, otherwise the water inside will evaporate and the strength will decrease. Even after curing, the strength of cement components will be affected by long-term exposure to high temperature.
Cement should be used up as soon as possible after mixing, otherwise it will be affected by temperature. Especially in winter, if it freezes, it will accelerate the hardening speed and its function will be destroyed.
How to make white cement stronger
Many people don't know how to make white cement stronger, so today Bian Xiao will tell you this question.
Without affecting the construction strength, the less water is added, the stronger the white cement is. Because in the process of adding water to adjust white cement, only a part of water and cement will react chemically, and the excess water will easily produce pores when mixed with concrete, which will reduce the strength. Fill the white cement, water it after 8 hours, and water it continuously for a week, so that the white cement can exert its strength.
Before using white cement, check whether the white cement on the packaging bag is within the shelf life, then take out a little white cement and twist it with your fingers to see if the product is still in a delicate state and observe whether it is caked and discolored by moisture. Note: Be sure to wear a mask before unpacking to avoid unnecessary harm to human body by inhalation.
The cement is too dry. Does it work?
Many people don't know whether cement and cement are too dry. Let's talk about this problem together!
Mixing different varieties and grades of cement;
1, concrete strength cracking will occur due to different setting time.
2. Mixing the high grade with the low grade will make the concrete strength lower than the high grade and higher than the low grade, so it is impossible to judge whether it meets the requirements when testing the concrete block.
3. Mixing special cement with ordinary cement will reduce the efficacy of special cement.
4. Mixing white cement with ordinary cement will lose the characteristics of white cement.
The above is about whether the white cement is hard when it is dry, how to make the white cement stronger, and whether the cement can be used if it is too dry. I hope I can help you!
