Products Description
Huaxuan KH-204 is a high-performance polycarboxylate superplasticizer, as the third-generation new type of concrete superplasticizer, because of its high water-reducing rate, high strength, low shrinkage, low bleeding and low slump loss and other properties Advantages, polycarboxylate water reducer has relatively good adaptability with different cements.Compared with naphthalene-based superplasticizers, the early and late strengths of polycarboxylate superplasticizers increase faster, especially for high-strength concrete.
Product Features
Good water-reducing rate: The product has good water-reducing performance at low dosage, especially in high-grade concrete (above C50), and its highest water-reducing rate can reach 45%;Excellent plastic retention performance: Because the steric hindrance of the extended polymer side chain effectively hinders the secondary agglomeration between cement particles, the product has high dispersion performance and can maintain this performance for a long time, realizing concrete mixing. The compound has excellent plastic retention ability.Good early strength and reinforcement effect: Under the same conditions, the early strength and reinforcement effect of concrete mixed with this product are higher than other types of superplasticizers.Greatly improve the durability of concrete: the low alkali content of this product, and because the water reducing agent is an air-entraining water reducing agent, it can significantly reduce the alkali-aggregate reaction of concrete and improve the freeze-thaw resistance of concrete.Dimensional stability: The concrete mixed with this product has effectively improved its shrinkage and creep properties, has good high dimensional stability, and reduces the risk of cracks.
Application
HUAXUAN KH-204 is suitable for cast-in-place concrete, reinforced concrete, ready-mixed concrete or pumped concrete in industrial and civil buildings, roads, bridges, ports, power stations, airports and other projects.HUAXUAN KH-204 can be used to formulate high-strength, high-performance, large-volume vibration-free self-compacting and other special concrete.
How to use
DOSAGE
Usually,the product dosage range is 0.3%-1.0% of the cementitious material.
Recommended dosage: In general, the recommended dosage for concrete batching plants is 0.4% of the cementitious material. {The specific dosage needs to be adjusted according to the materials}

INSTRUCTIONS
HUAXUAN KH-204 polycarboxylate high-performance water reducer is usually diluted with water into a liquid with a solid content of about 10%-20% before use.
For example, add water(750 kg) to HUAXUAN KH-204(205 kg) ,and stir them evenly, you will get 1 MT water reducing agent ready to use.
At the same time, other admixtures can also be added to increase product performance.
For example, you can use HUAXUAN KH-204 to prepare Early stength high range water reducing agent/Concrete enhancer.
FORMULA:HUAXUAN KH-204 + sodium gluconate or sucrose + air entraining agent
When the daily average temperature is 20℃, the dosage of sodium gluconate is 4-8% of KH-204.
When the daily average temperature is above 30℃, the dosage of sodium gluconate is 8-12% of KH-204.
If sucrose is used as retarder, the dosage is half of sodium gluconate, and the dosage of air-entraining agent is 0.02% of KH-204.
When the daily average temperature is above 30℃, the dosage of sodium gluconate is 8-12% of KH-204.
If sucrose is used as retarder, the dosage is half of sodium gluconate, and the dosage of air-entraining agent is 0.02% of KH-204.
