Polycarboxylate Superplasticizer

What is Polycarboxylate Superplasticizer (PCE)

Polycarboxylate superplasticizer is a high-performance water reducing agent and a kind of cement dispersing agent in the application of cement concrete. Widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects. It is also suitable for projects with long construction time and high requirements for concrete slumps, such as nuclear power engineering. The product is environmentally friendly, non-flammable, non-explosive, and it can be safely transported by train and car.

Polycarboxylate superplasticizers overcome some of the drawbacks of traditional water reducer and have the potential of low dosage, good moisture retention, low concrete shrinkage, strong molecular structure, high performance, and high production process, and it does not use formaldehyde in the production process.

Polycarboxylate Superplasticizer Applications

  • This product is suitable for pumping concrete for long-distance transportation.
  • It is used to prepare ordinary concrete, high-performance concrete, high strength concrete, and super high strength concrete.
  • Formulate durable concrete with impermeability, high moisture retention, and freeze-thaw resistance requirements.
  • This product is suitable for the preparation of high fluidity concrete, self-leveling concrete, fair-faced concrete, and vibration-free self-compacting concrete.
  • It is suitable to configure various concretes with high fly ash and mineral powder.

Advantages of Polycarboxylate Concrete Admixture

The polycarboxylate concrete admixture imparts excellent workability, good strength development, and excellent durability to concrete.

1. Low dosage, high water reduction rate. The water reduction rate can reach 45%, which is suitable for high-performance concrete production;

2. The loss is small while the slump is light. In the case of ready-mixed concrete for about 2 hours, the slump loss will be controlled within 15% by the application of it, which is beneficial to pumping construction and the long-distance transportation of commercial concrete.

3. After adding the polycarboxylic acid-based water reducing agent, the concrete has good workability. In the high slump, the concrete does not significantly separate or bleed, and the color of the concrete is uniform. It is conducive to the preparation of high-flow concrete and self-leveling concrete.

4. After the use of polycarboxylate water reducer, concrete shrinkage is relatively low, which can reduce the degree of concrete shrinkage and improve the durability and stability of concrete.

5. The polycarboxylate admixture has the characteristics of green environmental protection and non-toxic and harmless. It is conducive to the sustainable and healthy development of the construction industry.

6. It has good compatibility with various types of cement, good slump retention performance of concrete, and prolonged concrete construction time.

7. More slag or fly ash can be used instead of cement to reduce costs by adding polycarboxylate concrete admixture.

Instructions for Using Polycarboxylate Superplasticizers

  • The amount of it is 0.4% to 2.5% of the total weight of the cementitious material, and the usual dosage is 0.8% to 1.5%. Carrying out concrete tests before use for optimum dosage.
  • It should not be mixed with naphthalene superplasticizer. When using polycarboxylate concrete admixtures, mixers that have used naphthalene-based superplasticizers must be rinsed clean, otherwise, the water reduces effect might be lost.
  • When the polycarboxylate admixture is used, it may be directly added as a stock solution or may be formulated into a solution having a certain concentration.
  • Due to the large water reduction rate of the polycarboxylate concrete superplasticizers, the slump is highly sensitive to water consumption, and the water consumption must be strictly controlled during use.
  • Polycarboxylate based superplasticizer has good adaptability to most types of cement, but it is possible for individual cement to have a low water reduction rate and a large slump loss. In addition, the fineness and storage time of the cement may also affect the use of the polycarboxylate superplasticizer. At this time, it is recommended to solve the problem by appropriately increasing the dosage or compounding other retarding components.
