sodium lignosulfonate superplasticizer are surfactants. After they are added to concrete, the hydrophobic groups are directionally adsorbed on the surface of cement particles, so that the cement has a negative charge. The cement particles with the same charge are mutually repulsed and dispersed under the action of charge repulsion. The flocculent structure formed by the cement at the initial stage of adding water becomes a dispersed structure, and the free water in the flocculent condensate is released, so as to achieve the purpose of water reducing agent.

Mainly export for Concrete:
Polycarboxylate superplasticizer is a new type of water reducing agent. The water
reduction rate is generally around 20%, but it has high requirements for cement and sand of concrete.If the mud content in the sand is slightly larger, the polycarboxylate superplasticizer has a water reduction rate of 0.However, the technical team found that when using polycarboxylate superplasticizerâ??s dosage is 6% of weight with sodium lignosulfonateâ??s dosage 4%-6%,the water reduction rate will reach the most ideal water reducing ratio and the cost of concrete admixture is also the most economical.Because of the characteristics of calcium and magnesium ions in Sodium lignosulfonate, it is easy to occur precipitation and discoloration when mixed with polycarboxylate superplasticizer.
