KH-YQJ Air Entraining Admixture for Concrete
✓ Reduces surface tension during concrete mixing
✓ Generates independent closed microbubbles
✓ Improves workability and reduces bleeding
✓ Supports frost resistance, impermeability and durability
Product Preview
KH-YQJ is an air-entraining admixture for concrete. Through its special air-entraining structure, it significantly reduces the surface tension of aqueous solutions and generates independent closed microbubbles during concrete mixing.
The product is soluble in water and has good compatibility with polycarboxylate superplasticizers. By introducing beneficial microbubbles, it helps minimize concrete segregation and bleeding while improving workability, impermeability, frost resistance and corrosion resistance.

Improved Concrete Workability
Stable entrained air helps the concrete mixture move more smoothly and reduces harshness during placement.
Reduced Segregation and Bleeding
The microbubble structure helps stabilize the mixture and reduce common defects caused by water separation.
Better Durability
Beneficial microbubbles improve impermeability, frost resistance and corrosion resistance, helping concrete perform in demanding environments.
Transportation Infrastructure
Suitable for railway, highway and bridge concrete where workability and durability are required.
Airport and Port Engineering
Useful for concrete exposed to severe service environments, freeze-thaw risk or high durability requirements.
Marine Concrete
Can support durability improvement in marine and port projects when used in a tested concrete mix design.
What does KH-YQJ do in concrete?
It introduces small closed air bubbles, improving workability and helping the concrete resist freezing, permeability and corrosion problems.
Can it be used with PCE superplasticizer?
Yes. The product has good compatibility with polycarboxylate superplasticizers, but air content and slump should always be verified by trial mix.
Is higher air content always better?
No. Air content should match the project specification. Excessive air may reduce strength, so dosage must be controlled through testing.
Keep KH-YQJ sealed in clean containers. Protect it from contamination, freezing, high heat and direct sunlight during storage and transport.
The recommended addition level should be decided by trial mix according to the target air content, cementitious system, aggregate condition and admixture combination. Measure air content, slump and strength before production use.
