Can pure cement be used? What s the use?

Pure cement is very brittle after curing, so it is generally not used alone in construction, and can be used to gloss the surface of cement. There is also the ability to plug leaks, and the 'leak filling king' on the market is high-grade quick-drying cement.

White cement can be used as cement and can be used for non-load-bearing floors or for painting interior and exterior walls.

White cement uses calcium silicate as the main ingredient, which is a white hard cementitious inner material made of silicate clinker with very little iron content after bleaching treatment and adding an appropriate amount of gypsum grinding. This kind of white cement is mainly used in the decoration of the ground, stairs and exterior walls, or it is also necessary to add this white cement when making terrazzo, and white cement is also used when marble and tile inlays, which is different from the use of ordinary cement.

Precautions when using white cement1. The white cement should be used as much as possible after unpacking, so as to prevent moisture and deterioration.

2. White cement must be stirred with very clean water when using.

3. When using white cement, water should be added successively and stirred continuously.

4. Be sure to wear waterproof gloves when using white cement, which can protect our hands.

5. The white cement must be used at one time, otherwise it will affect the decoration effect.

6. After the construction is completed, the wall can not be squeezed hard, and the wall must be protected.

Summary. Why use concrete instead of pure cement Hello dear,!<

Because the amount of cement is too large, the dry shrinkage of concrete is large, and the heat of hydration is large, which is easy to lead to cracking of concrete. At the same time, cement is wasted and the project cost is increased. When using cement to prepare mortar, the general cement grade is much larger than the strength grade of the mortar, so a small amount of cement can meet the strength requirements.

However, when the amount of cement is small (such as less than 350kg), the fluidity and water retention of the mortar are often very poor, especially the water retention. Therefore, it seriously affects the construction quality of the mortar, so some cheap other cementitious materials are often added to improve the fluidity of the mortar, especially the water retention. Hope it helps!

The walls were plastered with lime mortar, and after a few months, irregular reticular cracks appeared, while protruding radial cracks appeared in different parts. How can this be improved.

Hello dear,!<

The wall strip was plastered with lime mortar, and after a few months, irregular reticular cracks appeared, and radial cracks protruding from Youshou appeared in different parts. How to improve the lime sand three-slurry plastering surface of the zero cause of the six bulging cracking The main reason: the base wall absorbs the moisture in the mortar, so that the mortar shrinks and increases, and the cracking phenomenon occurs; In addition, the water in the mortar will overflow through the pores in the mortar after turning into water vapor, and if the mortar is relatively dense, the gas is not easy to overflow, which will lead to the occurrence of bulging.

Cement is one of the indispensable materials in construction projects, it is divided into white cement and black cement, and there is a big difference between these two types of cement, so you must pay attention to it when using. So, can white cement be used as cement? What should I pay attention to when using white cement and black cement?

Let's take you to find out.

If it is used on indoor non-load-bearing floors or interior and exterior walls, it is fine, but if it is used on load-bearing floors or walls, it is definitely not possible. Because the strength of white cement will be relatively weak, it cannot be used on load-bearing walls, otherwise it will affect its strength and threaten the safety of the house.

Precautions for the use of white cement and black cement.

The nature of the use between white cement and black cement is not the same, so the two cannot be mixed together. If the two are mixed together, then for the floor slab that lacks waterproofing function, it will start to be waterproof.

How to use and inspect white cement.

Before the use of white cement, its shelf life should be verified, and the inner and outer packaging must be inspected. Check to see if the production date is consistent with the date on the package, the purpose of this is to prevent the use of expired white cement, which will affect the quality of the construction. In addition, when using white cement, it is necessary to understand how to use it and master its fineness.

How to use white cement and precautions.

Before using white cement, it is necessary to clarify its use method, as well as the specific precautions for construction. For white cement, it needs to be used all at once after opening, and if it can't be used all, then the remaining material is sealed in a plastic bag to prevent moisture or deterioration.

The article is always the old wheel: The above is all about whether white cement can be used as cement and what needs to be paid attention to when using white cement and black cement, I hope it will be helpful to you. If you want to know more about it, please stay tuned to Qeeka Home.

1. White cement can be used as cement.

2. However, it can be used on indoor non-load-bearing floors or interior and exterior walls, but if it is used on load-bearing floors or walls, it is definitely not possible.

3. Because the strength of white cement will be relatively weak, it can be used on the load-bearing wall without limb posture, otherwise it will affect its strength and threaten the safety of the house.

And because the nature of use between white cement and black cement is different, it is not possible to mix the two in one rush and use it carefully.
