Introduction of Kingsun Polycarboxylate Superplasticizer

As a professional PCE superplasticizer manufacturer in China, Kingsun can provide three different types of polycarboxylate superplasticizers for you, they are PCE powder, PCE (High Water Reduction) liquid, PCE (High Slump Retention) liquid. Compared with naphthalene superplasticizers and common water-reducing agents, PCE admixture has many technical features.

1. PEC Powder. PCE powder is a free-flowing, sandy, spray-dried powder. It has the characteristics of high fineness, excellent dispersibility, low gas content, good adaptability with various cements, and improved fluidity of mortar, etc. It is a new generation of polycarboxylate ether polymer, which can be used as a superplasticizer for cement-based materials. Polycarboxylate powder is also an excellent dispersing plasticizer for mineral materials such as gypsum and ceramics.

2. High Water Reduction. PCE water reducer is a ready-to-use liquid superplasticizer. It is light yellow in appearance. Besides, it can be completely water easily. The water reduction efficiency of PCE concrete admixture can be up to 25%. It is mainly used in the ready-mixed and precast concrete industries where the highest durability and performance is required.

3. High Slump Retention. PCE-High Slump Retention is a new generation superplasticizer for concrete. It contains polycarboxylate ether polymers and is specially formulated for ready-mix concrete where slump retention, high strength and durability are required in hot climates. It is chloride-free, meets SS EN 934, Set retarding/high range water reducing/superplasticizing admixtures, and ASTM C 494 requirements for Type F & G. It is also compatible with all cements meeting the ASTM standards. As an ideal admixture for the ready-mixed concrete industry, PCE superplasticizer has the ability to work with a low water/cement ratios and still obtain extended slump retention to make high-quality concrete.

Main Advantages of Polycarboxylate Ether (PCE)

Polycarboxylate Ether (PCE) superplasticizers are advanced chemical additives used in the construction industry to improve the workability and performance of concrete. These additives offer several advantages that contribute to the enhancement of concrete properties and construction practices. Here are some key advantages of PCE concrete admixture:

  • Compatibility with Various Cement Types. PCE superplasticizers are compatible with a wide range of cement types, including ordinary Portland cement, blended cement, and even specialty cements. This versatility makes them suitable for various construction applications and projects.
  • High Water Reduction. PCE superplasticizers are highly effective in reducing the water-cement ratio in concrete mixtures. This leads to increased strength, improved durability, and reduced permeability of the concrete. The reduced water content also contributes to the concrete’s overall sustainability by conserving water resources.
  • Improved Workability. These superplasticizers significantly enhance the workability of concrete by improving its flow and reducing viscosity. This increased workability makes concrete easier to place, shape, and finish, even in intricate forms and complex architectural designs.
  • Enhanced Strength Development. Kingsun polycarboxylate superplasticizers promote the early-age and long-term strength development of concrete. By reducing the water content while maintaining proper hydration, they contribute to higher compressive strengths, making the concrete more robust and durable over time.
  • Flexibility in Design. The improved workability and flowability provided by PCE superplasticizers allow for greater flexibility in design and construction. Complex architectural shapes, thin sections, and intricate detailing become more achievable due to the fluidity and ease of concrete placement.
  • Reduced Shrinkage and Cracking. The enhanced workability and reduced water content provided by PCE superplasticizers contribute to minimizing drying shrinkage and the likelihood of cracking in the cured concrete. This is especially important in ensuring the longevity and structural integrity of the finished construction.
  • Energy Efficiency. Concrete production often requires a substantial amount of energy. By enabling the use of lower water-cement ratios, PCE superplasticizers contribute to reducing the overall cement content in concrete mixtures. This, in turn, helps to lower the carbon footprint associated with concrete production.
