What is the strongest ratio of white cement to water?

The less water used, the higher the intensity.

The abbreviation of white Portland cement, which is made of white hydraulic cementitious material made of calcium silicate as the main ingredient and clinker with less iron content added to an appropriate amount of gypsum and ground finely. When grinding cement, it is allowed to add limestone that does not exceed 5% of the weight of cement. White cement is mostly used for decoration, and its manufacturing process is much better than that of ordinary cement.

It is mainly used to hook the gaps of white porcelain tiles, and is generally not used on the wall, because the strength is not high. It is available at the building materials market or at the decoration material store.

Where the raw meal of the appropriate composition is burned to partial melting, the obtained clinker with calcium silicate as the main ingredient and less iron content is added to the appropriate amount of gypsum and ground to make a white hydraulic cementitious material, which is called white Portland cement (referred to as white cement).

When grinding cement, it is allowed to add limestone that does not exceed 5% of the weight of cement. Note: It is allowed to add grinding aids that do not damage the performance of cement to grind cement, and the amount added does not exceed 1% of the weight of cement. The incorporation of other admixtures must be tested and submitted to the Ministry of Building Materials Industry for approval.

No matter what kind of cement it is, the less water you use and the higher the strength without affecting the construction requirements.

Because only part of the water used in normal cement construction has a chemical reaction with cement, and the rest of the excess water is lost, evaporated, wrapped in concrete and finally produced pores.

White cement is often used in building construction, white cement is often said in the industry Portland cement, the main component is calcium silicate, a small amount of gypsum is added in the firing process, ground and made, so how to make white cement stronger? What problems should I pay attention to when using it?

1. How to make white cement stronger.

Under the requirement of not affecting the construction intensity, the less water added, the stronger the white cement. Because the white cement fails in the process of adding water to adjust, only a part of the water and the cement will have a chemical reaction, and the excess water is mixed into the concrete and is easy to produce pores, resulting in a decrease in strength. After filling the white cement, it is watered with water after 8 hours, and the white cement is continuously watered for a week to maximize the strength.

2. Precautions for using white cement.

Before using white cement, check whether the white cement is in the holding period on the packaging bag, then take out a little white cement, twist it with your fingers to see whether the product is still in a delicate state, and observe whether there is moisture agglomeration, discoloration and other phenomena. Note: Be sure to wear a mask before unpacking, so as not to inhale the lead and cause unnecessary harm to the human body.

White cement should be used as soon as possible after unpacking, in order to avoid moisture and deterioration, if the use of deteriorated cement will affect the decoration effect, causing mold, falling off and other hazards. If you can't use it all at once, put the remaining white cement in a plastic bag and seal it to prevent moisture or deterioration.

In the process of use, it is necessary to stir it evenly with clean water to avoid improper operation and uneven white cement. And wear waterproof gloves to protect our hands.

Conclusion of the article: The above explains how to make white cement stronger and the precautions for use, I hope it will be helpful to you. White cement is often used in life, and it is also good to understand the precautions, so as not to affect the overall decoration effect.

1. Under the requirement of not affecting the construction intensity, the less water added, the stronger the white cement.

2. Because only a part of the water and cement will have a chemical reaction in the process of adding water to the white cement, the excess water mixed into the concrete is easy to produce pores, resulting in reduced strength.

3. After filling the white cement, water it will be watered after 8 hours, and the trapped person will be sentenced to a week to make the white cement exert its maximum strength.

Before using white cement, check whether the white cement is in the retention period on the slag of the packaging bag, then take out a little bit of white cement, twist it with your fingers to see if the product is still in a delicate state, and observe whether it has changed to be damp, agglomerate, discoloration and other phenomena.

As long as the construction can be carried out smoothly, the less water there is, the stronger it will be.

The bottom of the toilet bowl is fixed with white cement.

The following matters should be paid attention to in the use of white cement:

1) When preparing concrete with white cement, the coarse and fine aggregates should be white or colored marble, limestone, quartz sand and stone chips of various colors, and other impurities should not be mixed with other impurities, so as not to affect its whiteness and color.

2) The construction and maintenance method of white cement is the same as that of ordinary Portland cement, but the bottom layer and mixing tools must be cleaned during construction, otherwise the decorative effect of white cement will be affected.

3) When the white cement slurry is brushed, it is necessary to ensure that the base layer is moist and the coating is maintained in time. In order to accelerate the solidification of the coating, 1% 2% anhydrous calcium chloride can be added to the cement slurry, or 7% of the cement quality of leather glue can be added to improve the cohesion of the cement slurry and solve the problems of cement slurry depowdering, being washed and falling off.

4) The alkali saturated solution formed by the white cement in the process of hardening will precipitate white crystals such as calcium hydroxide and calcium carbonate (called hoarfrost) on the water surface after drying, and the low temperature and humid and windless state can promote the appearance of hoarfrost and affect its whiteness and brightness.

Kiss! Hello, happy to answer your <>

The ratio of white cement concrete is as follows: the ratio of white cement to ordinary cement is generally 1:2.

But the color of various cements is different, and the color of concrete is different for different grades. Therefore, it is necessary to adjust several times on the basis of this proportional wheel in order to adjust the suitable repair mixed cement. Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand and gravel, mixed with chemical admixtures and mineral admixtures when necessary, matched in appropriate proportions, and hardened by uniform stirring, dense molding and curing.

Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; The hard state after hardening, i.e., hardened concrete or concrete. The concrete strength grade is divided by the standard value of cubic compressive strength, and the strength grade of ordinary concrete in China is divided into 14 grades

C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80. Hope mine can help you <>

Do you have any other questions?

The <> of white cement should be blended according to the ratio of 1 (cement): 1 (Shijing water and glue): 2 (sand).

The typical characteristics of white cement are that it has a high whiteness, bright color, mainly used for building decoration materials, white cement will be used in many places for home decoration, plastering and filling leaks, etc., such as the loss of white cement improper use will lead to kitchen and bathroom leakage. Walls and ceilings appear crispy, falling off or peeling off. Loosening of the veneer material.

Therefore, the requirements for sand in the process of blending white cement are also relatively strict, and they need to be carefully screened before they can be used.

Typically, we can use a concrete sealant to increase the hardness of cement, and the same material is suitable for white cement.

White terrazzo floor after curing.

The concrete sealing curing agent material can effectively penetrate into the concrete for 5-8mm, and chemically react with a large amount of hydrated unfinished calcium and magnesium ions to form silica sol, and then seal the hardened concrete structure and increase the hardness and wear resistance of the concrete. And after grinding and polishing, it can create a strong as steel and bright as a mirror.
