Product Overview

PCE-L-HR High Water-Reducing PCE Liquid is a high-performance concrete superplasticizer developed by GoChem based on new-generation comb-shaped copolymer technology. It features ultra-high water reduction rate and excellent dispersion retention performance, specially designed for high-grade concrete, precast elements and high-fluidity concrete. Through optimized molecular structure, it achieves excellent water reducing effect at low dosage, significantly improves early and late strength of concrete, while improving concrete workability.

Key Features

1. Ultra-high water reduction: Up to 40% water reduction, effectively reduces concrete water-binder ratio, significantly improves concrete strength at all ages

2. High dispersibility: Strong dispersion ability for cement particles, excellent concrete workability, no bleeding or segregation

3. Rapid early strength development: Significantly improves concrete early strength, especially suitable for precast elements and fast-curing concrete construction

4. Wide adaptability: Good compatibility with different types of cement and admixtures (fly ash, slag, silica fume, etc.)

5. Low shrinkage: Effectively reduces concrete drying shrinkage, improves concrete volume stability and durability

6. Eco-friendly: Free of formaldehyde, chloride and other harmful substances, no corrosion to steel bars, meets environmental requirements

Applications

- High-strength concrete (C60-C100 and above)

- Precast concrete elements (pipe piles, box girders, sleepers, etc.)

- Self-compacting concrete (SCC)

- High-flow pumped concrete

- Key projects such as high-speed railways, bridges, tunnels

- Steam-cured concrete products

Recommended Dosage

- Normal dosage is 0.8%-1.5% of total cementitious materials weight, optimal dosage should be determined through on-site trial mixing

- Concrete mix proportion test is recommended before use, adjust dosage according to raw material conditions and construction requirements
