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:
PCE Superplasticizer Powder. White PCE polycarboxylate superplasticizer powder is a new-generation, environmentally friendly high-efficiency water-reducing agent for mortar, produced using advanced synthesis and drying technologies. Specifically, its main component is polycarboxylate, and the material takes the form of a free-flowing powder. In addition, it offers strong overall performance and supports more environmentally responsible construction applications. As a result, its superplasticizing properties can improve concrete workability and durability. When incorporated into concrete mixtures, it enhances flowability and supports the production of concrete with complex designs and smoother finishes. Furthermore, it helps reduce the water-cement ratio, which can contribute to stronger and more durable structures.
PCE Superplasticizer – High Water Reduction. The high-water-reduction grade is a light-yellow liquid. In particular, it can significantly reduce cement water demand while improving concrete fluidity and crack resistance after hardening. As a result, this liquid formulation works well in non-shrink grouting, repair mortar, and other cement-based applications. Furthermore, its strong water-reducing performance supports more efficient concrete production and helps meet the growing demand for durable and resource-efficient construction.
PCE Superplasticizer – High Slump Retention. The high-slump-retention grade is a clear, transparent liquid designed to improve concrete workability and maintain a high slump over an extended period. What’s more, it performs well in hot environments, where concrete can lose workability more quickly. Therefore, it helps maintain concrete fluidity for longer and gives construction teams greater flexibility during transportation, placement, and finishing. In addition, its extended workability can support smoother construction operations and more consistent placement quality.

Polycarboxylate superplasticizer offers multiple advantages that improve concrete performance and construction efficiency. In particular, it enhances workability, supports strength development, improves durability, and provides greater flexibility in concrete formulation. These characteristics make it an important admixture for modern construction applications.
(1) High Water Reduction
Polycarboxylate admixture can significantly reduce the water requirement of concrete mixtures. This allows concrete producers to achieve the required workability with less mixing water. As a result, the admixture helps optimize the water-cement ratio and supports efficient concrete formulation.
(2) Improved Workability
PCE polycarboxylate superplasticizer increases concrete flowability while reducing viscosity. Therefore, workers can place, shape, and finish concrete more easily. This benefit proves particularly useful for complex architectural designs, densely reinforced structures, and confined spaces.
(3) Enhanced Strength Development
The admixture supports both early-age and long-term strength development. Specifically, it helps concrete maintain effective cement hydration while controlling the water content. As a result, concrete can develop higher compressive strength and meet demanding structural requirements.
(4) Minimized Segregation
These superplasticizers improve the cohesion and uniformity of concrete mixtures. They help keep cement paste and aggregates evenly distributed during mixing, transportation, and placement. Consequently, the concrete mix maintains more consistent properties and reduces the risk of segregation.
(5) Increased Durability
Polycarboxylate superplasticizer can improve concrete durability by helping create a denser internal structure. In particular, the resulting concrete can show lower permeability and better resistance to freeze-thaw cycles, chemical attack, and abrasion. This makes the admixture suitable for concrete exposed to demanding service conditions.
(6) Versatile Construction Designs
Improved flowability gives concrete greater flexibility for complex construction requirements. For example, contractors can use suitable mixes for intricate architectural shapes, narrow sections, and structures with complicated geometries. This versatility expands the range of concrete design and placement options.
(7) Reduced Shrinkage and Cracking
Proper use of polycarboxylate superplasticizer can help control drying shrinkage and reduce the potential for cracking. In addition, improved workability allows concrete crews to achieve more uniform placement and consolidation. Together, these benefits support the overall integrity of hardened concrete.
(8) Compatibility with Various Cement Types
Kingsun PCE superplasticizer works with a wide range of cement types. Therefore, users can select suitable formulations for different concrete applications and cement compositions. However, compatibility testing remains important when users introduce a new cement or change raw materials.
(9) Energy Efficiency
PCE superplasticizer can help optimize concrete formulations by reducing water demand and, under suitable mix-design conditions, lowering the cement content required to achieve the target performance. This approach may reduce the energy associated with cement production and improve material efficiency.
(10) Sustainable Construction
PCE superplasticizer supports resource-efficient concrete production. For example, its high water-reduction capability can lower mixing-water demand, while optimized mix designs may reduce cement consumption. In addition, these benefits can help concrete producers improve material efficiency and support more sustainable construction practices.
1. The recommended dosage of polycarboxylate superplasticizer ranges from 0.5% to 1.6%. For special cement types or aggregates, adjust the dosage according to the actual mix requirements and trial results.
2. Add the product to the measured mixing water, then introduce the mixture into the concrete mixer together with the water. To achieve effective water reduction, we recommend a mixing time of at least 150 seconds.
3. When you use the product for the first time or change the cement type, conduct a trial mix based on the site raw materials and construction conditions. Then, determine the appropriate dosage and concrete mix ratio according to the test results. This process helps maintain consistent concrete quality.
4. PCE superplasticizer provides a high water-reduction rate, so concrete slump responds strongly to changes in water content. Therefore, carefully control both water consumption and admixture dosage during mixing and construction.
5. Do not mix polycarboxylate-based superplasticizer with naphthalene-, melamine-, amino-, or other types of water-reducing agents. Such combinations may significantly reduce the performance of the admixture system.
