These issues need to be paid attention to to avoid misunderstandings during the use of concrete admixtures.

The improvement of concrete performance is inseparable from the use of admixtures, so admixtures play an indispensable role in improving the performance of concrete. However, the application effect of admixtures is affected by a variety of factors. Therefore, when choosing to use admixtures, you must pay special attention to some matters:

1. Admixtures Selection

Select the appropriate type of admixture according to the construction engineering design and engineering construction regulations. Admixtures should be tested before use and selected based on the effect and your own economic conditions. The admixtures used must have the following documents produced by the delivery company:

1. Product manual, and the key ingredients of the product should be marked;

2. Factory inspection report and certificate of conformity;

3. Characteristics test report of concrete mixed with admixtures.

2. Composite application of admixtures

When several types of admixtures are used in composite applications, they should be Pay attention to the compatibility between different types of admixtures and their impact on concrete properties. Test before applying the same, and use it in combination according to the actual effect. For example, polysulfamate performance additives and naphthalene-based additives cannot be used in combination.

3. Safety precautions

It is prohibited to use applications that cause harm to the body or harm the natural environment. Contaminated admixtures. Users should pay attention to the relevant information on concrete admixture safety precautions provided by the processing plant and follow them.

4. Usage standards

For concrete structures and concrete with usage performance regulations, they should Strictly control the chloride ion content and the total number of alkali in concrete according to relevant standards. The chloride ion content and total alkali content in concrete refer to the sum of the sulfate and alkali content of its various raw materials.

5. Precise quantity control

Because of the properties of polysulfamate performance admixtures The mixing amount has a great impact on its properties, and users should pay attention to accurate measurement and verification.
