Import polycarboxylate superplasticizer

1.What is polycarboxylate superplasticizer?

Concrete polycarboxylate superplasticizer refers to the fact that after adding it, it can reduce the water demand of concrete under the condition of maintaining basically the same fluidity, thereby improving the strength and durability of concrete, or in the condition that the amount of cement used and the water-cement ratio remain unchanged. , adding concrete fluidity, admixtures to improve concrete workability.

2.What’s the functions for polycarboxylate superplasticizer?

Lubrication effect: The polar hydrophilic groups in the water reducer are oriented and adsorbed on the surface of cement particles, and are easily associated with water molecules in the form of hydrogen bonds. 

The force of this hydrogen bond association effect far exceeds the molecular attraction between water molecules and cement particles. When the cement particles absorb sufficient water reducing agent, the surface layer of the cement particles forms a stable layer of solvated water by virtue of the association effect of R-SO3θ and the hydrogen bonds in the water molecules, plus the hydrogen bond association between the water molecules. 

The film plays a three-dimensional protective effect, blocks the direct contact between the cement particles, and plays a lubricating effect between the particles.

  •  Wetting effect: After the cement is mixed with water, the surface layer of the particles is wetted by water, and its wet condition has a great influence on the characteristics of freshly mixed commercial concrete. amount that can be reduced.
  • Water reduction effect. After adding a polycarboxylate superplasticizer to the commercial concrete, the water-cement ratio can be significantly reduced under the condition of maintaining fluidity. The water reducing rate of high-efficiency water-reducing agent can reach 10% to 25%, while the water-reducing rate of ordinary water-reducing agent is 5%-15%, and high-efficiency polycarboxylate superplasticizer is also famous for this. The reason for the water reducing effect is mainly because of the adsorption and dispersion effect of commercial concrete on the water reducing agent.
  • Plasticizing effect. After adding a polycarboxylate superplasticizer to the commercial concrete, the fluidity can be added under the condition that the water-cement ratio remains unchanged. The usual water-reducing agent can increase the slump of freshly mixed commercial concrete by more than 10 cm under the condition that the amount of cement used remains unchanged.

3.How to import polycarboxylate superplasticizer?

Usually the polycarboxylate superplatsicizer will be packed in drum (for liquid), and if for powder it could be packed as 25kgs/bag. As polycarboxylate superplasticizer with many different types, you may need to send us very accurate requirements or better can send us the specification for we can check for you. 

Right now we mainly producing 2 types of products: Water reducing and slump retention. To import polycarboxylate superplasticizer, it’s very important to find a stable supplier with mature technology. We know that the stable and good quality is very important for longer business, for all the chemicals, we have very strict inspection before deliver out.

For any demands please send us imquiry freely, and we will contact with you as quickly.
