Aqueous polycarboxylate polymer solution acting as a superplasticizer for reduced water and improved concrete durability.
PRODUCT DETAILS
PCE (POLYCARBOXYLATE ETHER) 300KG – NEW-GENERATION SUPERPLASTICIZER FOR CONCRETE
PCE (Polycarboxylate Ether) is a new-generation superplasticizer for concrete that significantly reduces water demand and improves flowability and durability. It is used in high-strength, self-compacting and ready-mix concrete.
PRODUCT INFORMATION / Introduced packaging: 300 kg/drum. The product is an aqueous polymer solution. Acceptance criteria must be based on the COA of the actual batch delivered.
1. What Is PCE (POLYCARBOXYLATE ETHER) 300KG?
PCE (Polycarboxylate Ether) is a synthetic polycarboxylate-based polymer used as a high-range water-reducing admixture (superplasticizer) for concrete. Through electrostatic and steric dispersion mechanisms, PCE disperses cement particles well, reduces mixing water, and improves flowability and durability. The product is usually supplied as a 40–50% solids solution for high-strength, self-compacting and ready-mix concrete.

4. Applications
4.1. Ready-Mix and Self-Compacting Concrete
- Superplasticizer for ready-mix concrete.
- Self-compacting concrete (SCC) and pumped concrete.
- High-performance and ultra-high-performance concrete (HPC/UHPC).
- Precast and prestressed concrete.
- Mass concrete requiring slump retention.
4.2. Mortar and Other Products
- Admixture for dry-mix and self-levelling mortar.
- Admixture for masonry and tile adhesive mortar.
- Component in concrete blocks and precast elements.
- Admixture for sprayed mortar and grouts.
4.3. Special Structures
- Admixture for marine, hydraulic and transport concrete.
5. Instructions for Use
- Recommended dosage 0.2 – 1.2% by weight of binder; determine by mix-design trials.
- Add PCE to the mixing water after 50 – 90% of the water has been added.
- Do not pre-mix with other admixtures; dispense separately when used together.
- Mix thoroughly to ensure homogeneous dispersion before placing concrete.
- Carry out concrete trials before full-scale production.
6. Safety, Storage and Transportation
- Wear safety goggles, gloves and protective clothing when handling the product.
- Avoid prolonged eye and skin contact; the product is water-based with mild alkalinity.
- Store in a dry, cool place, protected from freezing and direct sunlight.
- Keep containers closed when not in use to avoid contamination and water evaporation.
- Keep out of reach of children; not for food use.
- In case of eye contact, rinse immediately with plenty of clean water for at least 15 minutes.
- If frozen during cold storage, thaw slowly at room temperature and stir well before use.
- Dispose of waste and wastewater according to environmental regulations.
7. Selection and Acceptance Criteria
- Verify the COA of the actual delivered batch against the technical requirements.
- Check appearance, colour, clarity and visible impurities.
- Check container condition, seals, labels and traceability information.
- Review the SDS for storage and emergency handling.
- Check homogeneity, water-insoluble matter and batch-specific parameters.
8. Frequently Asked Questions
• What is PCE and what is it used for?
PCE is a polycarboxylate-based superplasticizer for concrete that reduces water and improves flowability.
• What is the recommended dosage?
The recommended dosage is 0.2 – 1.2% by weight of binder, determined by mix-design trials.
