1. Naphthalene based Superplasticizer has a significant effect of reducing water dispersible, water reduction rate of 18% or more and can improve the fluidity of cement paste at low water-cement ratio.

2. Keep the watercement ratio constant, can greatly improve the workability of concrete, namely to improve the flow of concrete nor bleeding segregation, improve bond strength steel and concrete,the concrete surface smooth.

3. In the same slump and keep the original strength of the same conditions, the agent is mixed with 0.5% -1.0 cementitious materials, can save 15% -25% of cement.
