What is the role of water reducing agent in concrete

1. Mixing concrete when you can add a certain amount of water reducing agent, after mixing evenly,

   can improve the fluidity of concrete, make its structure more stable, improve the strength,

   but also to ensure that when the strength of concrete does not change, save the amount of cement,

   so water reducing agent is an indispensable additive in concrete.

   
   

2. When adding, it is also necessary to note that it can not be added at will. 

Attention should be paid to the fact that although it can improve the strength 

and save the amount of cement, it is necessary to choose the appropriate reducing

water agent products. The higher the water reduction rate, the better. 

It should be selected according to the actual demand.

3, if the water reduction rate is increased, the strength of concrete will be higher and higher, 

but if the content of water in concrete is reduced, it is easy to shrink, 

easy to dry, but to reduce the use of water reducing agent
