Polycarboxylate superplasticizer, also known as PCE superplasticizer, offers excellent advantages such as high water reduction, good flowability, and wide formulation adaptability. For different cement-based systems, gypsum-based systems, and concrete applications, different PCE grades should be selected according to the raw materials, performance requirements, and working conditions.
To help customers choose the right product more efficiently, Botai Chemical offers different PCE superplasticizer grades for cement-based systems, gypsum-based systems, and concrete applications. These products can be selected according to different performance priorities, such as water reduction, slump retention, flowability, open time, and formulation stability.
1. C-Type PCE Superplasticizer for Cement-Based Systems
C-type PCE superplasticizers are mainly suitable for ordinary cement, low-aluminate cement, high-aluminate cement, and ultra-high-performance concrete systems.
| Grade | Form | Key Features and Advantages | Typical Applications |
| P-121C | Powder | High water reduction rate above 25%, good flowability, strong formulation compatibility, and stable storage performance | Grouting mortar, duct grouting material, bearing mortar, repair mortar |
| P-130C | Powder | Optimized for sulphoaluminate cement and high-aluminate cement, wide pH adaptability, good flowability, and good mechanical performance | Cement-based self-leveling mortar, floor leveling mortar |
| P-160C | Powder | Extremely high flowability with good retention, long working time, and no bleeding | Ultra-high-performance concrete, UHPC |
| P-715 Slump Retention Type | Powder | Significantly improves open time and slump retention, while enhancing mortar or concrete strength | Cement-based mortar or concrete requiring longer working time |
2. G-Type PCE Superplasticizer for Gypsum-Based Systems
G-type PCE superplasticizers are suitable for natural gypsum, desulfurized gypsum, and phosphogypsum systems.
| Grade | Form | Key Features and Advantages | Typical Applications |
| P-350G | Powder | Broad adaptability to different gypsum systems with good stability | Gypsum-based self-leveling mortar and most gypsum-based products |
| P-308G | Powder | More stable performance based on P-350G, higher water reduction rate, and better compatibility with other additives | Gypsum-based products with higher requirements for performance and stability |
3. Special PCE Series for Concrete Applications
For concrete applications, flake or powder PCE products can be selected according to different performance priorities, such as water reduction, slump retention, or balanced performance.
| Grade | Form | Key Feature | Selection Recommendation |
| P-136W | Flake | Water-reducing type, mainly focused on water reduction performance | Suitable for high-strength concrete and low water-to-binder ratio systems |
| P-172S | Flake | Slump retention type, mainly focused on maintaining workability | Suitable for long-distance transportation or high-temperature conditions where flowability retention is required |
| P-150 | Flake | Balanced type, offering a balance between water reduction and slump retention | Suitable for most conventional concrete systems with strong general applicability |
Practical Selection Notes
The above recommendations are based on practical application experience. In real projects, the final performance of PCE superplasticizer may be affected by many factors, including cement type, gypsum source, other additives, temperature, mixing process, and construction conditions.
In some cases, C-type and G-type products may also be used across different systems after proper compatibility testing. Therefore, customers are strongly advised to conduct application tests using their actual local raw materials before confirming the final grade.
Contact Botai Chemical for PCE Superplasticizer Selection
Choosing the right PCE superplasticizer is not only about selecting a product grade, but also about matching the additive with your cement, gypsum, aggregate, formulation design, temperature, and final application requirements. If you are producing self-leveling mortar, grouting material, UHPC, gypsum-based products, or ready-mix concrete, Botai Chemical can help recommend a suitable PCE grade based on your actual raw materials and performance targets.
Whether you need higher water reduction, better flowability, longer slump retention, improved strength development, or better formulation stability, our technical team can provide product selection support, sample testing guidance, and customized formulation suggestions.
