Polycarboxylate Superplasticizer

Polycarboxylate superplasticizer (PCE) is an advanced chemical additive used in the construction industry to enhance the performance of concrete. As a new generation of high-performance superplasticizer, this superplasticizer is developed after the common water reducing agent represented by wood calcium and the high-efficiency superplasticizer represented by naphthalene series. At present, PCE is a superplasticizer with the best application prospect and the best comprehensive performance. So it can be widely used in highways, bridges, dams, tunnels, high-rise buildings, and other projects.

With the construction of large-scale infrastructure such as nuclear power, water conservancy, bridges, tunnels, etc., especially the implementation of planning and railway passenger dedicated line network projects, the market demand for PCE polycarboxylate superplasticizers will show a trend of continuous growth.

As a new type of green concrete admixture, Kingsun polycarboxylate superplasticizer is very suitable for high-strength concrete, high-performance concrete, mass concrete and high-quality fluid plastic concrete. And PCE superplasticizer has the features of water reduction, slump retention, reinforcement, shrinkage resistance, and environmental protection. In addition, it can also be compounded with various admixtures into multifunctional concrete admixtures, such as pumping agent, early strength agent, impermeable waterproofing agent, retarder, etc.

Kingsun Polycarboxylate Superplasticizer (PCE) for Sale

As a leading manufacturer of PCE based admixture in China, Kingsun can provide three types of polycarboxylate concrete admixtures and factory price for all the customers. They are PCE liquid for high water reduction and PCE liquid for High Slump Retention, and PCE powder. Although their appearance and specifications are different, the water reduction rate of polycarboxylate based superplasticizer can reach more than 25%. The following is the detailed introduction:

  • White PCE polycarboxylate powder is a new generation of environmentally friendly high-efficiency water reducing agent for mortar based on new synthesis technology. The main component is polycarboxylate, which is a fluid powder made by special drying technology. And its comprehensive indicators are excellent, green and pollution-free, so PCE superplasticizer powder is the high-performance environmentally friendly product. And its superplasticizing properties lead to improved concrete workability and durability. Incorporating PCE powder into concrete mixtures enhances flowability, allowing for the creation of intricate designs and smoother finishes. This powder reduces the water-cement ratio, leading to stronger and longer-lasting structures.
  • PCE based superplasticizer (High Water Reduction) is the light yellow liquid, it can greatly reduce the water consumption of cement, increase the fluidity of concrete, and improve the crack resistance of cured cement. It can be widely used in non-shrinkage grouting, repair mortar, etc. As the demand for sustainable, efficient, and resilient structures grows, the high water reduction PCE liquid emerges as an indispensable tool for construction professionals, reshaping the way we build for the future. 
  • Polycarboxylate superplasticizer (High Slump Retention) is clear transparent liquid. It is designed to enhance concrete workability and maintain a high slump for extended periods.What’s more, PCE superplasticizer also shows great performance in hot environments. Its unique ability to extend the workability of concrete, while maintaining a high slump, empowers construction professionals with greater flexibility, control, and efficiency. As the demands of modern construction continue to evolve, this innovative additive stands as a testament to human ingenuity, pushing the boundaries of what’s achievable in concrete placement and finishing.

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

Polycarboxylate superplasticizer offers a host of advantages that significantly improve concrete properties and construction practices. Their ability to increase workability, strength, and durability while supporting sustainable construction makes them a crucial component in modern construction projects.

  • High Water Reduction. polycarboxylate admixture can significantly reduce the water-cement ratio in concrete mixtures. This leads to increased concrete strength, durability, and reduced permeability. The lowered water content also improves the concrete’s sustainability by conserving water resources.
  • Improved Workability. PCE polycarboxylate superplasticizers greatly enhance the workability of concrete by increasing its flowability and reducing viscosity. This makes it easier to place, shape, and finish concrete, even in complex architectural designs and confined spaces.
  • Enhanced Strength Development. They contribute to both early-age and long-term strength development in concrete. By reducing water content while maintaining proper hydration, they lead to higher compressive strengths, resulting in stronger and more durable concrete.
  • Minimized Segregation. These superplasticizers improve the cohesion of concrete mixtures, preventing the segregation of aggregates and water. This results in a more uniform mixture, reducing the risk of inconsistent properties within the concrete.
  • Increased Durability. The lower water-cement ratio and improved strength achieved through polycarboxylic acid superplasticizer can enhance the durability of concrete. This leads to reduced permeability and higher resistance against factors such as freeze-thaw cycles, chemical attacks, and abrasion.
  • Versatile Construction Designs. Polycarboxylate water reducer enables the construction of intricate architectural designs and complex shapes due to their enhanced workability and flowability. This versatility in design adds flexibility to construction projects.
  • Reduced Shrinkage and Cracking. The improved workability and reduced water content provided by polycarboxylate superplasticizers help minimize drying shrinkage and the potential for cracking in the cured concrete, enhancing the structural integrity of constructions.
  • Compatibility with Various Cement Types. Kingsun PCE superplasticizer is compatible with a wide range of cement types, making them suitable for various construction applications and projects, including those that involve different cement compositions.
  • Energy Efficiency. By enabling lower water-cement ratios, PCE superplasticizers contribute to reducing cement content in concrete, which can lower energy consumption during production and reduce the carbon footprint associated with concrete manufacturing.
  • Sustainable Construction. PCE superplasticizers align with sustainable construction practices by conserving water, reducing cement usage, and contributing to environmentally friendly building practices.

1. The recommended dosage range of polycarboxylate superplasticizer is 0.5%-1.6%, and the dosage range can be adjusted appropriately for special cement or aggregate.

2. It can be mixed into the metered water and added to the concrete mixer at the same time with water. In order to achieve a good water reduction effect, we recommend that the mixing time is at least 150s.

3. When using this product for the first time or changing the cement type, the necessary trial mixing test should be carried out according to the site raw materials and construction conditions, and the mixing amount and construction mixing ratio should be determined according to the test results to ensure the quality of the concrete.

4. Due to the high water reduction rate of PCE superplasticizer, its concrete slump is very sensitive to the water consumption, and the water consumption and dosage must be strictly controlled during use.

5. Polycarboxylate based superplasticizer should not be mixed with naphthalene, melamine, amino and other water reducing agents, otherwise the performance index will be significantly reduced.
