POLYVIA™ PCE Flake is a 97–98% high-solid polycarboxylate superplasticizer designed for efficient transportation, local liquid preparation and flexible concrete admixture formulation.
High Solid Content · Local Liquid Preparation · Flexible Formulation · Efficient Logistics
PCE Flake (Polycarboxylate Ether Flake) is a 97–98% high-solid polycarboxylate superplasticizer supplied in concentrated flake form. It can be dissolved in water to prepare liquid PCE for concrete admixture production and formulation.
Solve the practical challenges of importing, storing and formulating liquid PCE with a high-solid, locally convertible PCE solution.
Conventional liquid PCE contains a significant proportion of water. High-solid PCE Flake concentrates the active material, making long-distance transportation more efficient.
PCE Flake can be dissolved locally to prepare liquid PCE at the required solids content, giving producers greater control over local supply.
Compared with liquid PCE, concentrated PCE Flake reduces the storage volume required for an equivalent amount of PCE solids and simplifies inventory management.
Use F980 for high water reduction, F970 for slump retention, or develop a suitable blend according to cement chemistry, transport time and concrete performance targets.
Less water to ship. Less space to store, More flexibility to formulate
A smarter PCE supply model for customers who want to prepare and optimize liquid PCE locally.

Customers can ship concentrated PCE and prepare liquid PCE locally when required, improving logistics and supply flexibility.
Choose according to the main concrete performance requirement:
F980 — High Water Reduction: for strong initial dispersion, reduced water demand and low W/B concrete.
F970 — Slump Retention: for extended workability during transportation, pumping and placement.
Where both are required, F980 and F970 can be blended and optimized through concrete trials.
For 98% solid PCE Flake, approximately 960 kg of water is required to prepare a true 50% solid solution:
1,000 kg PCE Flake + 960 kg Water → 1,960 kg PCE Liquid at 50% solids
For practical preparation, adding 1,000 kg water produces approximately 2,000 kg of ~49% solid PCE Liquid.
Yes. After the flakes are completely dissolved and the solution is homogeneous, the prepared PCE Liquid can be dosed directly into concrete.
The optimum dosage should be determined according to cement chemistry, W/B ratio, SCMs and target concrete performance.
Both are high-solid forms of PCE, but they are designed for different handling and application needs.
PCE Flake is particularly suitable for local preparation of PCE Liquid and concrete admixture formulation, offering a concentrated form for efficient transportation and storage.
PCE Powder is easier to dose directly into dry-mix formulations such as mortar, grout and self-leveling compounds.
For customers primarily producing liquid concrete admixtures or concrete, PCE Flake is often the more practical choice.
Yes. This is particularly useful in ready-mix, pumped and long-transport concrete where both initial water reduction and workability retention are required.
Use F980 as the HWR component and F970 as the SR component, then optimize the ratio according to initial slump, required retention time, temperature and cement compatibility.
Yes. PCE Flake can be dissolved in water to prepare different liquid concentrations according to formulation requirements. The flake-to-water ratio should be calculated from the actual solid content and target concentration.
Store PCE Flake in a cool, dry and well-ventilated place, protected from moisture and excessive heat. Keep the packaging tightly sealed to minimize softening or agglomeration during storage.
PCE Flake offers a high-concentration alternative to conventional liquid PCE, reducing the amount of water transported and improving shipping efficiency. After delivery, it can be dissolved in water to prepare PCE Liquid locally for concrete use or admixture formulation.
