Polycarboxylate Superplasticizer Powder
JF POLYCARBOXYLATE SUPERPLASTICIZER POWDER 02 is created through the polymerization of various large organic molecules and is specially designed for applications in cement grouting and dry mortar. This versatile product exhibits excellent compatibility with cement and other additives. Its notable attributes include the ability to improve fluidity, enhance the strength of the final set, and reduce cracks in solidified mortar. As a result, it finds utility in a range of applications, including non-shrinkage grouting for cement, repair mortar, grouting for cement-based flooring, waterproof grouting, crack-sealing, and the production of expanded polystyrene insulation mortar. Moreover, it also finds extensive use in gypsum, refractory materials, and ceramics.
Features of Polycarboxylate Superplasticizer Powder (PCE Powder)
High water-reducing rate: It can make the mortar water-reducing rate reach more than 20%, and greatly improve the fluidity of the mortar under the condition of the same amount of water added to the mortar.
Early-strength and high-strength: It can improve the early strength and ultimate strength of mortar, and is the best choice for various applications that require rapid curing.
High durability: reduce the water-binder ratio of mortar, improve durability, reduce shrinkage and creep, and reduce shrinkage and cracking in the later stage of mortar curing.
Green and environmental protection products: the production process does not produce pollution to the natural environment, in line with ISO14000 international environmental protection management standards.

Uses of Polycarboxylate Superplasticizer Powder (PCE Powder)
Concrete Admixture:
Water Reduction: PCE powder significantly reduces the water content needed in concrete mixtures while maintaining or enhancing workability. This results in higher strength and durability of the concrete.
Improved Workability: It enhances the fluidity of concrete, making it easier to pour and handle, especially in complex formworks and intricate architectural designs.
High-Performance Concrete: Used in the production of high-strength and high-performance concrete for demanding construction projects, including skyscrapers, bridges, and infrastructure projects.
Self-Compacting Concrete (SCC):
Enhanced Flowability: PCE powder is crucial in the production of self-compacting concrete, which can flow and consolidate under its own weight without the need for mechanical vibration. This is particularly useful for projects with dense reinforcement or complex shapes.
Reduced Segregation: It helps prevent the segregation of the concrete mix, ensuring a uniform distribution of aggregates and cement paste.
Precast Concrete:
Fast Setting and Early Strength: PCE powder is often used in precast concrete elements to accelerate setting times and achieve early strength, allowing for faster turnaround times in production and installation.
Surface Finish Quality: It improves the surface finish of precast elements, reducing the need for additional finishing work.
Ready-Mix Concrete:
Extended Workability: In ready-mix concrete applications, PCE powder helps maintain workability over longer periods, which is essential for transportation and placement at construction sites.
Consistency: It ensures consistent quality and performance of the concrete mix, batch after batch.
High-Performance Mortars and Grouts:
Enhanced Flow and Adhesion: PCE powder improves the flow and adhesion properties of mortars and grouts, making them easier to apply and more effective in filling gaps and voids.
Durability: It increases the durability and longevity of mortars and grouts used in construction and repair applications.
Shotcrete:
Improved Pumpability: PCE powder enhances the pumpability and sprayability of shotcrete, which is used in tunneling, mining, and slope stabilization.
Reduced Rebound: It reduces the rebound (waste material that falls off during application), ensuring more efficient use of materials.
Polycarboxylate Superplasticizer Powder (PCE Powder) FAQs
How does PCE Powder work?

What are the benefits of using PCE Powder in concrete?
Improved Workability: Enhances the fluidity and workability of concrete.
Water Reduction: Significantly reduces water content while maintaining workability.
Strength: Increases compressive and flexural strength.
Durability: Enhances the durability and longevity of the concrete.
Efficient Mixing: Provides better mix stability and uniformity.
In what forms is PCE Powder available?
PCE Powder is available in powder form, which is easy to transport, store, and handle. It can be directly added to the dry mix or dissolved in water before mixing.
How is PCE Powder different from other superplasticizers?
PCE Powder offers superior performance compared to traditional superplasticizers like naphthalene or melamine-based admixtures. It provides higher water reduction, better slump retention, and improved early and final strength of concrete.
What is the typical dosage of PCE Powder?
The typical dosage ranges from 0.1% to 0.3% by weight of cement. However, the optimal dosage depends on the specific requirements of the concrete mix and should be determined through laboratory testing.
Can PCE Powder be used in all types of concrete?
Yes, PCE Powder can be used in various types of concrete, including ready-mix, precast, high-performance, and self-compacting concrete. It is versatile and suitable for different applications and performance requirements.
How should PCE Powder be stored?
