The interaction between admixtures and cement:

The main function of admixtures is to improve the performance of concrete by adding corresponding admixtures to concrete, thereby promoting the improvement of construction quality and efficiency of construction projects. The reason why admixtures can promote the improvement of various properties of concrete is that they can produce mutual effects with concrete. Usually, the mutual effects between admixtures and concrete are adaptable, matching and compatible. Since the main components and the proportions of various components in admixtures are quite different, the adaptability between different admixtures and concrete will also be quite different. Admixtures with poor adaptability may not only cause low water reduction rate of concrete, but also cause the concrete to set too fast, thus affecting the normal construction of the project. Admixtures with good adaptability can effectively improve the water reduction rate of concrete and avoid cracking and cracking of concrete to a certain extent. The matching of admixtures and concrete will affect the adsorption efficiency of concrete to admixtures. If the matching of admixtures and concrete is low, the adsorption efficiency of concrete to admixtures will be extremely low, which will also affect the various effects of its admixtures. The compatibility of admixtures with concrete will affect the efficiency of the use of admixtures. If the compatibility of admixtures with concrete is poor, concrete will not be able to blend with admixtures, which will lead to the waste of some admixtures.

Suggestions on the selection principles of premixed concrete admixtures:

1. Concrete admixture manufacturers need to have perfect pre-sales and after-sales services. When selling concrete admixtures, concrete admixture manufacturers should focus on relevant factors, establish relatively complete concrete admixture technical documents as much as possible, provide concrete admixture instructions, and ensure that the sale of concrete admixtures is carried out within the scope of available technical support.

2. Choose the right admixture quality. When choosing premixed concrete admixtures, it is necessary to master the detailed applicable varieties and dosages of admixtures. Find relatively suitable concrete admixtures in comparative tests, choose high-quality admixtures as much as possible, and give full play to the role of concrete admixtures.

3. Choose a metering scheme suitable for production automation. Choosing a metering scheme suitable for production automation is also one of the important principles for the selection of premixed concrete admixtures.

4. Selecting admixtures with high economic benefits The selection of admixtures with high benefits is to better meet the construction and production needs of construction units. It should be in line with the current status of construction units, have certain comprehensive analysis characteristics, meet the economic index coefficient requirements of construction units to a certain extent, and have the economic benefit characteristics. Therefore, this admixture selection scheme is deeply recognized by construction units.
