KH-204 Polycarboxylate Superplasticizer Liquid Additive for Concrete

Exceptional Water Reduction Performance

KH-204 effectively disperses cement particles and reduces the water demand of concrete mixtures. With a measured water reduction rate of 34%, it enables lower water-cement ratios while maintaining excellent workability.

Lower water consumption contributes to improved compressive strength, reduced permeability, and enhanced durability of hardened concrete.

Excellent Workability and Dispersion

KH-204 rapidly adsorbs onto cement particles, preventing flocculation and releasing trapped water within the cement system.

The enhanced dispersion improves:

• Concrete fluidity;
• Pumpability;
• Placement efficiency;
• Surface finish quality.

These characteristics support stable production in both ready-mix plants and precast operations.

Enhanced Early and Long-Term Strength

KH-204 promotes efficient cement hydration and matrix densification.

The balanced strength development supports both accelerated construction schedules and long-term structural performance.

Broad Compatibility with Cementitious Systems

KH-204 demonstrates excellent compatibility with:

• Ordinary Portland cement;
• Composite cement;
• Fly ash systems;
• Ground granulated blast furnace slag (GGBFS);
• Mineral admixture blends.

It can also be formulated together with:

• Retarders;
• Defoamers;
• Air-entraining agents.

This flexibility allows producers to adapt admixture systems to local raw materials.

Improved Concrete Durability

By lowering the water-binder ratio and improving microstructural compactness, KH-204 contributes to:

• Reduced drying shrinkage;
• Lower cracking risk;
• Improved impermeability;
• Enhanced freeze-thaw resistance;
• Reduced reinforcement corrosion risk.

Its low chloride and alkali characteristics support long-term durability requirements.

Customizable Performance Solutions

Different projects require different admixture performances.

KH-204 formulations can be optimized for:

• Slump retention;
• Early strength development;
• Retarding effects;
• Viscosity modification;
• Mud resistance.

Customized support helps concrete producers maintain stable quality despite variations in cement, aggregates, and environmental conditions.

Ready-Mixed Concrete

KH-204 improves workability and production consistency in commercial ready-mix concrete operations.

Its excellent dispersion properties help maintain stable concrete quality throughout batching, transportation, pumping, and placement.

High-Strength Concrete

Low water-binder ratios are essential for high-strength concrete.

KH-204 enables substantial water reduction while maintaining workability, supporting the production of structural concrete with enhanced mechanical properties.

Precast Concrete

Precast manufacturers require both flowability and early strength development.

KH-204 contributes to improved mold filling, reduced vibration requirements, and faster turnover of precast elements.

Roads and Highway Construction

Concrete pavements and infrastructure projects benefit from improved durability and strength development.

KH-204 supports stable production for large-volume construction activities.

Bridges and Tunnel Engineering

Bridge decks, tunnel linings, and transportation infrastructure often require concrete with excellent pumpability and durability.

KH-204 helps improve placement efficiency while contributing to long-term structural performance.

Industrial and Civil Buildings

KH-204 is suitable for a wide range of residential, commercial, and industrial construction projects requiring reliable concrete performance.

What is the recommended dosage of KH-204?

The recommended dosage is 0.20%–1.00% of the total cementitious materials. The optimum dosage should be determined through laboratory trial mixes.

Can KH-204 be used with fly ash and slag?

Yes. KH-204 exhibits excellent compatibility with common supplementary cementitious materials, including fly ash and ground granulated blast furnace slag.

Does KH-204 improve early strength?

Yes. KH-204 supports early strength development, with compressive strength ratios reaching 177% at 1 day under standard testing conditions.

Is KH-204 suitable for precast concrete?

Yes. Its combination of workability enhancement and early strength gain makes it suitable for precast concrete production.

Can KH-204 be customized for specific projects?

Yes. Customized formulations can be developed to provide slump retention, retardation, early strength enhancement, viscosity control, or mud resistance.

Will KH-204 cause reinforcement corrosion?

No. KH-204 does not contain substances that present corrosion hazards to steel reinforcement under normal usage conditions.

KH-204 is supplied in IBC ton barrels for convenient storage, transportation, and on-site handling.

Recommended storage conditions:

• Store in a dry and well-ventilated environment;
• Avoid prolonged exposure to direct sunlight;
• Keep containers tightly sealed after opening;
• Protect the product from contamination during handling.

The recommended shelf life is 12 months from the date of manufacture. If the product has exceeded the recommended storage period, testing and verification should be conducted before use.

According to the TDS, KH-204 can be supplied in 1000 kg IBC tanks and 200 kg barrels according to project and shipping requirements.

KH-204 may be added directly together with the mixing water or diluted according to the requirements of the batching system.

The recommended dosage range is 0.20%–1.00% by weight of cementitious materials. The exact dosage should be established through laboratory trial mixes based on cement characteristics, aggregate properties, environmental conditions, and performance requirements.

For best results, users are encouraged to conduct compatibility testing before large-scale production.
