As the "monosodium glutamate" in the cement industry, cement grinding aids have been widely recognized and applied in numerous cement enterprises, bringing significant economic and social benefits. However, overall, the quality of cement grinding aid production enterprises varies greatly, and the cement grinding aid market is mixed with good and bad. Therefore, the correct selection of grinding aid products by cement enterprises is crucial for the stability of cement quality and energy conservation and emission reduction of cement enterprises.

The selection of cement grinding aid products should follow the following six principles:

1、 Quality stability principle. The dosage of cement grinding aids in cement is relatively small (<0.5%), and the fluctuation of their quality has a significant impact on the final quality of cement products. So when choosing cement grinding aids, it is necessary to strictly examine the process status, quality control status, scientific research and development capabilities, etc. of the grinding aid production enterprise, to see if its quality control system is sound and if the quality control measures are in place, in order to ensure that the quality of cement grinding aid products is uniform and stable. It is best to choose enterprises that have passed the quality management system certification.

2、 Principle of cost-effectiveness. When choosing a cement grinding aid, do not just look at the product quotation, but also consider the cost-effectiveness of the cement grinding aid. Industrial tests should be conducted to verify product performance, calculate the input-output ratio, and select the cement grinding aid with the highest cost-effectiveness.

3、 Comply with national standard principles. In addition to meeting the industry standard requirements of JC/T667-2004 for cement grinding aids, the cement produced after adding grinding aids must comply with the national standard requirements of GB175-2007, especially the harmful component chloride ion content must be ≤ 0.06% to ensure the durability of cement concrete.

4、 The principle of adaptability. The adaptability of cement grinding aids and concrete admixtures must be fully considered, that is, the cement and concrete admixtures added with grinding aids must have good adaptability and construction performance. 

5、 Principle of improvement. The role of cement grinding aids in the cement production process is not omnipotent, and their effects and effects vary with the process conditions and raw materials of cement enterprises. When choosing cement grinding aids, it is also necessary to consider whether the cement grinding aid production enterprise has the ability to continuously improve its products, that is, to examine the scientific and technological research and development capabilities of the cement grinding aid enterprise, and whether it has a high-quality R&D team and fully equipped technical equipment.

6、 Service principle. The correct use of cement grinding aids is crucial. When selecting a cement grinding aid manufacturer, it is important to fully consider their technical service level, whether the service is in place, etc., to ensure the correct use of cement grinding aids.
