For the use of cement additives to be reasonable
Cement additive is an important guarantee for cement manufacturers to produce cement because it helps grinding, improves production efficiency, enhances cement performance and reduces production cost. The main principle is to increase the output of the mill, make the raw materials fully ground, enhance the strength of the finished cement, increase the amount of mixed materials, and reduce the cost of cement production through the effectiveness of the additives themselves. Cement additives certainly have their good effects, but companies can not blindly use, according to their own actual situation (such as cement ingredients, mill models, etc.) for cement additives to make appropriate adjustments in order to make the best performance of cement additives.

Development trend of cement additives
With the continuous development of society, the process technology is also improving, and the requirements of the cement industry are getting higher and higher. Cement additives have the advantages of saving energy, reducing costs, and improving the quality of cement products and their corona, and have been commonly used at home and abroad.
How to use concrete admixtures correctly
At present, the variety of additives, the role of different in the concrete, including water reducing agent dosage is the largest, occupying a major position. The following is a personal experience of the application of water reducing agent.
Concrete admixtures so many, you are using the right?
Water reducing agent can maintain the concrete slump under the condition of unchanged, reduce the amount of mixing water to improve the fluidity of the concrete mix, or reduce the amount of cement per unit, saving cement. According to the water reducing agent water reducing capacity is divided into ordinary water reducing agent (also known as plasticizer, water reduction rate of not less than 8% ), high efficiency water reducing agent (also known as super plasticizer, water reduction rate of not less than 14% ) and high performance water reducing agent (water reduction rate of not less than 25%).
Chemical admixtures for concrete
The so-called concrete chemical admixture, is mixed in the process of mixing concrete (can be mixed with the mixing water at the same time, can also be mixed with water lag) to improve the performance of concrete substances. The amount of admixture is generally not more than 5% of the mass of cement.
