What is PCE Flake?
Polycarboxylate Ether Flake is a concentrated solid form of polycarboxylate superplasticizer. After dissolving in water, it produces a high-performance liquid admixture capable of significantly reducing water demand while maintaining excellent workability and strength development.
Compared with conventional naphthalene-based and lignosulfonate-based water reducers, PCE Flake provides:
- Higher water reduction efficiency
- Better slump retention
- Lower dosage requirements
- Enhanced cement adaptability
- Superior concrete strength development
- Improved durability performance
Its comb-shaped molecular structure creates both electrostatic repulsion and steric hindrance effects, enabling superior cement particle dispersion.

FAQ
1. What is the difference between PCE Flake and PCE Liquid?
PCE Flake is a concentrated solid form of polycarboxylate ether. It must be dissolved in water before use and offers lower transportation and storage costs compared to liquid products.
2. Can PCE Flake be used directly in concrete?
Generally, PCE Flake is first dissolved in water to prepare a liquid admixture before being added to concrete.
3. Is PCE Flake chloride-free?
Yes. InnoNew® PCE Flake is manufactured without intentionally added chlorides and is suitable for reinforced and prestressed concrete applications.
4. What water reduction can be achieved?
Typical water reduction rates exceed 25%, depending on cement type, dosage, and mix design.
5. Is PCE Flake suitable for PHC spun piles?
Yes. PCE Flake is widely used in precast and prestressed concrete production, including PHC and PC spun pile manufacturing, where high strength and durability are required.
