Product Preview
PC-733E is a powder polycarboxylate ether superplasticizer produced by modifying polyether polymers and converting the liquid polymer into powder through a special spray drying process.
It is designed as a high-range concrete water reducer for ordinary concrete, high-performance concrete, mass concrete, and concrete systems containing large amounts of fly ash or mineral powder.
Compared with UHPC-specific powders such as PC-306E, PC-733E is positioned as a broader concrete powder water reducer. Its value lies not only in high water reduction but also in convenient powder handling, dry-blending compatibility, and stable dispersion in cement systems where mineral admixtures are used to improve cost, durability, and heat control.

Powder Water Reducer for Concrete Production
PC-733E is a powder PCE water reducer designed for concrete systems where dry admixture handling, storage stability, and flexible addition methods are important. It can be dry blended with powder materials or dissolved into a liquid solution before use, making it suitable for different batching and production arrangements.
High Water Reduction with Low Dosage
PC-733E provides a tested water reduction rate of 34%, helping reduce water demand, lower water-cement ratio, and improve concrete strength and durability. This makes it useful for ordinary concrete, high-performance concrete, and special concrete systems that need reliable workability with reduced mixing water.
Designed for Fly Ash and Mineral Powder Systems
A key difference of PC-733E is its suitability for concrete containing large quantities of fly ash or mineral powder. In these systems, dispersion efficiency and compatibility matter because mineral admixtures can change water demand, paste viscosity, and setting behavior. PC-733E helps improve fluidity while supporting compact hardened concrete.
Strength Development for General Concrete Applications
Test data shows compressive strength ratios of 177% at 1 day, 164% at 3 days, 155% at 7 days, and 143% at 28 days. This helps concrete producers balance water reduction, workability, early strength, and long-term performance.
Durability and Crack Resistance Support
By improving cement particle dispersion and reducing water demand, PC-733E enhances paste compactness, improves shrinkage and creep performance, helps reduce cracking risk, and improves concrete durability under suitable mix design conditions.
Ordinary Concrete
PC-733E can be used in ordinary concrete where improved workability, lower water demand, and better hardened performance are required. Its powder form is convenient for producers who prefer dry storage or premixed powder addition.
High-Performance Concrete
For high-performance concrete, PC-733E supports lower water-cement ratios and improved particle dispersion. Its tested 240 mm slurry fluidity and 34% water reduction rate help maintain workability while supporting strength development.
Mass Concrete
Mass concrete often uses mineral admixtures to manage hydration heat and durability. PC-733E is suitable for these systems because it can improve workability while supporting reduced water demand and compatibility with fly ash or mineral powder.
Concrete with High Fly Ash or Mineral Powder Content
PC-733E is especially relevant for concrete systems containing large quantities of fly ash or mineral powder. It helps improve dispersion and flowability in blended cementitious systems, supporting both fresh concrete workability and hardened compactness.
Special Concrete
PC-733E can also be used in other special concrete formulations where a powder polycarboxylate water reducer is preferred for storage, transportation, dry mixing, or on-site handling reasons.
How is PC-733E different from PC-306E?
PC-306E is positioned for UHPC systems with extremely low water-binder ratios and ultrafine powder dispersion requirements. PC-733E is a broader concrete powder water reducer for ordinary concrete, high-performance concrete, mass concrete, and concrete with high fly ash or mineral powder content.
Can PC-733E be dry blended?
Yes. PC-733E can be premixed with dry powder materials. The mixing process should ensure uniform powder distribution before adding water and fully stirring to reach the required concrete state.
Can PC-733E be dissolved before use?
Yes. PC-733E can first be dissolved into water to prepare a liquid solution with the required solid content, and then added to concrete according to dosage. The provided usage information notes that this addition method can provide a better effect.
What is the recommended dosage?
The recommended dosage is 0.10%–0.40% of the cementitious material. The optimum dosage should be determined through trial mixing according to concrete design requirements and actual raw material conditions.
Is PC-733E suitable for concrete with fly ash or mineral powder?
Yes. This is one of the important application differences of PC-733E. It is suitable for concrete containing large quantities of fly ash or mineral powder, where dispersion, flowability, and compatibility with blended cementitious systems are important.
PC-733E is packaged in paper-plastic composite bags, 25kg/bag.
Jumbo bag packaging can also be used according to shipping and project requirements. Typical loading capacity is approximately 20MT/20ft or 28MT/40HQ without pallets, depending on packing and logistics conditions.
The shelf life is 12 months from the date of production. If the shelf life has expired, testing and verification must be carried out before use.
Store in a well-ventilated and dry place. Prevent moisture, avoid direct sunlight, and seal the package promptly after opening to prevent moisture absorption and product deterioration.
The recommended dosage of PC-733E is 0.10%–0.40% of the cementitious material. The optimum dosage should be determined by trial mixing based on concrete design requirements, cement type, mineral admixture content, aggregate condition, and target workability.
Dry blend method: when conditions allow premixing in dry powder, add PC-733E according to the required amount and ensure uniform mixing of the powder system. Then add mixing water and stir fully to obtain the desired concrete state.
Pre-dissolution method: PC-733E can also be dissolved in water to prepare a liquid solution with the required solid content. This solution can then be added to concrete according to dosage. This method is often helpful when better dispersion and more uniform admixture distribution are required.
