After cement mixing with water, due to the effect of molecular gravity between cement particles, many flockers are produced, forming flocculation structure. In this structure, cement particles are wrapped around a lot of mixing water, thus reducing the workability of concrete mixture. At this time, if the right amount of water reducing agent, as a result of its surface activity, resulting in hate water base end directed adsorption on the surface of cement particles, hydrophilic base end points to aqueous solution, so that the surface of cement particles are with the same charge, increased the electrostatic repulsion between cement particles, resulting in cement particles dispersed each other. The flocculation structure disintegrates and the free water is released, thus effectively increasing the fluidity of the concrete mixture. On the other hand, as a result of reducing water agent to cement cent come loose action, make cement particle and water contact surface increase in quantity, hydration is more sufficient, can improve the strength of concrete thereby.

Specification：

Advantage：

1. Increased setting time at elevated temperature

2. Good adaptability to cement.

3. Longlasting control of slump loss

4.Set Retarding Type Polycarboxylate Superplasticizer 50% Improved workability without increased water content

5. Good fluidity at low dosage 

Performance： 

1. The water reduction rate is high, and the water reduction rate is above 25% ~ 40%.

2. Large flow, large slump, small loss when concrete slumps.

3. It has a significant hardening and reinforcing effect on concrete, and the three-dimensional strength can be increased by 50 to 100%.

The strength of 7d and 28d can be increased by 30-50%, and the later strength maintains a steady increase.

4. Fresh concrete has good workability, no segregation, good pumpability, and is lighter than solid concrete on the outside of hardening.
