What is the function of concrete admixture in engineering

What important role can concrete admixtures play in engineering? 

Concrete admixtures can not only meet the production requirements of segments, 

but also outperform aliphatic water reducing agents in the production process, 

strength and durability indexes of segments. 

The popularization and application of concrete admixture in precast segment industry 

has been developed rapidly in building materials coal mining industry.

It is necessary to use admixtures in concrete. Concrete admixtures are important materials 

to ensure the quality of the whole project. Adding concrete admixture in engineering can 

greatly improve the workability of concrete, increase the density of concrete, and then improve 

the strength and durability of concrete. Adding concrete admixture can improve the fluidity of 

the mixture. Space stabilization action, anchorage action to reduce slump loss; Electrostatic 

hindrance and steric hindrance effect. Under different seasonal conditions and temperature conditions, 

concrete admixtures have good adaptability and good slump retention performance.
