          Concrete Additives
          
Admixtures can improve the anti-carbonization performance of concrete. There is a certain linear relationship between the carbonation depth and porosity of concrete; admixtures have a great influence on the frost resistance of concrete.
          

          
Concrete with air-entraining and water-reducing agent is anti-freezing The performance is better, but the early strength agent alone has no effect on the frost resistance of concrete.
          

          
Concrete admixture is a chemical substance that is mixed in the process of mixing concrete and accounts for less than 5% of the cement mass, which can significantly improve the performance of concrete. The characteristics of concrete admixtures are many varieties and small dosages, which have a greater impact on the performance of concrete.
          

          
They have the characteristics of less investment, quick results, and significant technical and economic benefits. With the continuous advancement of science and technology, admixtures have been increasingly used, and admixtures have become the fifth important component of concrete in addition to the four basic components.
          

          
Admixtures are the fifth component of concrete. Adding admixtures can improve the workability of concrete and increase the strength and durability of concrete.
          

          
The characteristics of concrete admixtures are many varieties and small dosages, which have a greater impact on the performance of concrete. Therefore, its variety selection, application technology and quality control are more important than other concrete components
