Polycarboxylate Ether (PCE) PW888 HWR | High Water Reduction Concrete Superplasticizer
Polycarboxylate Ether (PCE) PW888 HWR is a high water-reducing superplasticizer engineered to deliver maximum strength, density, and durability.
Unlike standard admixtures, this advanced PCE superplasticizer enables low water-cement ratio concrete, making it ideal for precast, high-rise, and infrastructure projects.
Core Performance
Key Advantages of PW888 HWR:
- Ultra-high water reduction rate (30–45%)
- Significant compressive strength improvement
- Excellent cement dispersion efficiency
- Reduced porosity and permeability
- Enhanced durability in aggressive environments
Compared with traditional naphthalene-based superplasticizers, PCE offers better efficiency and long-term performance.

FAQ
Q1: What is HWR in PCE PW888?
HWR stands for High Water Reduction, meaning strong reduction in water content for higher strength concrete.
Q2: What is the difference between HWR and HSR?
- HWR: maximize strength
- HSR: maintain slump over time
Q3: Can PW888 be used for precast concrete?
Yes, it is ideal for high early strength and smooth finishing.
Q4: What is the dosage?
Typically 0.2–0.6%, depending on mix design.
