polycarboxylate superplasticizer water reducer slump retention retarder

Product Description

Huaxuan High-tech® KH***4 has excellent water reduction capacity,which can significantly reduce concrete water consumption by *5% to 45%, and improve the compressive strength of concrete at various stages. It can improve the workability of concrete while ensuring the ultimate strength and durability of concrete. It has good compatibility with different types of cement, and can be compatible with air entrainer and other admixtures. When used with other admixtures, each admixture must be separately mixed into the mixture.
 
KH***4 complies with The ASTM C **4 Norm
ASTM C **4, Type A and F

Scope of application
 
1.Precast, premix, long-distance transport, pumping concrete.
2.Ordinary concrete, high strength, high performance, ultra-high strength concrete, large volume vibration free self-compaction and other special concrete.
3.Widely used in industrial and civil buildings, roads, Bridges, port terminals, power stations, airports and other projects in cast-in-place concrete, reinforced concrete, ready-mixed concrete or pumped concrete.
 
What problems does the KH***4 help solve?
Concrete water-reducing agent is a kind of polymer surfactant, which can reduce the water consumption and increase the strength of concrete under the condition of constant concrete workability and cement dosage. Or under the same conditions of workability and strength, save the amount of cement.
1. Improve the workability of the concrete mix
· It has the function of adsorption dispersion, wetting and lubrication;
· Improve the fluidity and pumpability of concrete, thereby improving construction efficiency;
· Easy to mix, transport, water and shape;
· Blockage and delamination are not easy to occur during pumping;
2. Reduce the unit water consumption of concrete and improve the early strength
· The cement particles are dispersed, excess water is released, the fluidity increases, and the unit water consumption of the concrete mix decreases;
· Promote the hydration reaction of cement particles and accelerate the early strength development of concrete;
· Shorten maintenance time, improve construction efficiency, improve frost resistance and durability;
3. Reduce concrete bleeding and settlement, improve crack resistance
· Reduce the segregation of concrete and maintain the workability required for concrete construction;
· Improve the internal structure of concrete, improve the ductility and toughness of concrete, and reduce concrete shrinkage and cracking;
 
Uses

• When used, KH***4 can be directly measured and mixed into concrete at the same time with mixing water; It can also be diluted into a lower solid content, and then incorporated into concrete according to the corresponding amount;
• KH***4 The recommended dosage is 0.**1.0% of the cementing material, and the dosage should be determined after trial mixing according to the concrete design requirements and actual raw materials.
