What is a cement waterproofing agent? What are the characteristics and uses of cement waterproofing agent?
Cement waterproofing agent means that under certain conditions, it can prevent, delay or reduce the destruction of cold and heat bridge crystallization and chemical reaction on the surface or inside of concrete, and has good freeze-thaw resistance (such as thickening, emulsion stability, etc.). freezing point lowering admixture. The main components of cement waterproofing agent are: high-efficiency penetrating base layer treatment agent; multi-functional modified polymer rubber powder and its compound system; appropriate amount of active catalytic adjuvant.

What issues should be paid attention to when choosing a waterproofing agent manufacturer?
Nowadays, many people will go to manufacturers when purchasing waterproofing agents, but with the continuous increase in its demand, the number of companies in this area has also increased a lot. In this case, I believe that customers will become more difficult to choose. So do you know what are the few things to consider when choosing a waterproofing agent manufacturer? Regarding this issue, we will briefly introduce to you how to choose a waterproofing agent?

What are the advantages of waterproofing agent?
Water repellants are favored by major industries because of their own advantages. It is also very useful when used. So do you know what the advantages of waterproofing agents are? Next, I will give you a detailed introduction to this issue. If you are also interested, please take a look together.

Rapid setting agent for concrete admixtures
Accelerator: an admixture added to concrete that can quickly set and harden the concrete. The liquid alkali-free accelerator developed by our company is very rare in its application reports. This type of accelerator can solve some common problems of alkaline accelerators, such as the harm to the underground construction environment, the harm of alkali aggregate reaction, the harm of high pH value during use, and the loss of later strength of shotcrete. Its admixture only accounts for 2% to 3% of the cement content in the concrete, but it can make the concrete initially set within 5 minutes and finally set within 10 minutes. In order to achieve the purpose of emergency repair or rapid setting of concrete in wells. shotcrete construction method

Ten precautions for the application of admixtures in commercial concrete
1. Sodium polyphosphate and other retarders should be strictly controlled in dosage, and should not be excessive;
2. There should be a metering container for the admixture, and it must not be mixed out of control;
3. When using wood calcium as a retarder, the general dosage should not exceed 0.25% of the cement amount;
4. Chloride salt type antifreeze should not be used in the construction of reinforced concrete structures in winter;
5. When using pumping agent for ready-mixed concrete, the compatibility test of cement and admixture should be done in advance, and cement prepared with anhydrite and phosphogypsum should not be used;

Status Quo of my country's Additives Industry
The status quo of my country's foreign additives industry can be summarized as follows:
The variety of admixtures is complete, and there are almost all kinds of admixtures in foreign countries;
High-efficiency water-reducing agents have developed from a single naphthalene series to a variety of varieties, such as new varieties of sulfamate, polycarboxylate high-efficiency water-reducing agents, etc.;

The important role of admixtures
Use to solve emerging problems
Every tiny detail is worth paying close attention to, and every tiny action is an organic part of enterprise management. Now in the development of the construction field, people have more understanding of concrete admixtures. As a component of concrete admixture, its function is well known. With the continuous increase of the application amount of concrete admixture, some problems related to the application of the admixture are gradually exposed.

Wenshan 30,000-ton concrete admixture project was completed and put into operation
Our Evening News reporter learned from the Wenshan Economic and Commercial Bureau that because Wenshan and southern Yunnan have never had a certain scale of admixture manufacturers, they have always relied on Kunming or other supplies from outside the province. Wenshan Zhuangshan Industrial Co., Ltd. has rewritten this "blank history" after the completion and operation of the 10,000-ton concrete admixture device project. At present, the project has completed a total investment of 11.39 million yuan in fixed assets, employed more than 30 people, and has an annual output of more than 20,000 tons.
