Maintaining flowability and preventing segregation in complex formwork
Increased labor costs and compromised structural integrity
Project delays that impact budgets and timelines
Water reducers (superplasticizers) offer a robust solution to these challenges. As POLLYFLEX, a leading manufacturer, we want to share our expertise to help you succeed.
A water reducer, often referred to as a superplasticizer or high-range water reducer (HRWR), is a chemical admixture added to concrete to significantly enhance its workability without increasing the water content.
Think of it as a lubricant for concrete – it allows cement particles to slide past each other more easily, making the mix more fluid and easier to place.
These admixtures are essential in modern concrete technology, enabling the production of high-strength, durable, and easily workable concrete, particularly in applications where low water-to-cement ratios and high fluidity are required.

| Product Name | Effective Content (%) | Water Reduction (%) | Slump Retention (min) | Type |
|---|---|---|---|---|
| POLLYFLEX PCE-Flake 670 | 97% ± 1 | ≥ 25 | ≥120 | Premium |
| POLLYFLEX PCE-Flake 680 | 97% ± 1 | ≥ 25 | ≥120 | Water Reduction |

Note: Dosage is expressed as a percentage of cementitious materials by weight. Optimal dosage may vary depending on specific mix design and application conditions.
For general applications where moderate flowability and workability are needed. A standard PCE dosage provides adequate performance for most construction projects.
Used in complex geometries or heavily reinforced structures. Requires higher PCE dosage for exceptional flow and passing ability around reinforcement.
For high durability applications like marine environments or aggressive chemical exposures. Specialized PCEs used with other admixtures.
Key Benefit:
Reduces water content by up to 40%, leading to higher compressive strength and improved long-term durability.
Impact:
Denser concrete matrix, reduced permeability, increased resistance to freeze-thaw cycles and chemical attack.
Why it matters:
Creates stronger, longer-lasting structures, minimizing maintenance and repair costs.
Laboratory testing showing improved strength
Self-consolidating concrete flowing smoothly around reinforcement
Key Benefit:
Creates a highly fluid mix that effortlessly fills complex forms and encapsulates reinforcement without vibration.
Impact:
Reduces labor costs, speeds up construction time, and eliminates risk of honeycombing or air voids.
Why it matters:
Simplifies construction, reduces errors, and ensures consistent, high-quality results.
Key Benefit:
Maintains desired consistency and flowability of the concrete mix for extended periods.
Impact:
Provides ample time for placement, even in challenging conditions or large-scale pours.
Why it matters:
Reduces risk of cold joints, improves surface finish, and allows for more efficient construction logistics.

| Factor | Considerations | POLLYFLEX Recommendation |
|---|---|---|
| Desired Slump | Higher slump requires higher dosages or more effective superplasticizers | High slump (>200mm): POLLYFLEX PCE Flake 690 |
| Concrete Strength | Higher strength requires lower w/c ratios, best achieved with PCE | High-strength (>40 MPa): POLLYFLEX PCE Flake 670 |
| Environmental Conditions | Temperature and humidity affect superplasticizer performance | POLLYFLEX PCE Flake 670 adapts to wide range of conditions |
| Formwork Complexity | Intricate formwork needs excellent flowability and slump retention | POLLYFLEX PCE Flake 680 ideal for complex formwork applications |
Separation of concrete components during placement.
Solution:
Use POLLYFLEX PCE Flake 690 with good slump retention. Adjust dosage and consider VMA for improved stability.
Water rising to the concrete surface and thus cracking.
Solution:
Reduce water content and use POLLYFLEX PCE Flake 680. Ensure proper mix design and avoid over-vibration.
Difficulty achieving desired concrete flow.
Solution:
Increase dosage, switch to PCE, or adjust mix design. Consult POLLYFLEX technical support.
Add 0.5-1.4% by weight of cementitious material following manufacturer's recommendations.
Add to mixing water or directly into mixer. Ensure thorough mixing for uniform distribution.
Proper mixing procedures
Store in original containers in dry, cool area. Protect from freezing temperatures.
Wear appropriate PPE. Avoid direct skin contact and ensure adequate ventilation.
Success Key
Always perform trial mixes to determine optimal dosage.
Best Practice
Verify compatibility with other admixtures before use.
