A .concrete superplasticizer is new generation polycarboxylate seires high range water reducing admixture.
It combines macromers and small monomers of polyethenoxy ether through copolymerization of free radical.
It has extreme high water reducing ratio and low slump loss, which can guarantee high water reduction when making concrete, and is widely applied in pump concrete.

Polycarboxylate concrete additives
(1). Suitable to make early strength concrete, retarding type concrete, precast concrete, cast in situ concrete, large flow concrete, self-compacting concrete, mass concrete, high performance concrete and as-cast finish concrete, as well as precasting and cast in situ for various industrial and civil architecture. Especially suitable for low strength grading commercial concrete.
(2). Can be applied in high speed railway, nuclear power, water conservancy and hydropower projects, the subway, large bridges, highways, harbor pier and other major national projects.
(3). Suitable for commercial concrete agitate stand for any industrial and civil buildings.
Advantage of PCE
1.Low dosage, hstrength and high performance concrete.
2. When light slump loss is small: ready-mixed concrete 2h slump loss less than 15%, pretty good for long-distance transportation and pumping .
3. Concrete shrinkage: can significantly reduce shrinkage of concrete, significantly increase the volume of concrete stability and durability.
4. low content of salt,less than 0.2%.
5. With good stability: no precipitation at low temperatures.
6. Green products: non-toxic products, green products, contribute to sustainable development.
7.Good economic returns: Project total cost less than other types of products.
B: Sodium Gluconate:
Sodium Gluconate : as water stabilizer has excellent effects of corrosion and scale proof, it is widely used as water quality stabilizer, such as the treatment chemicals in the cooling cycle system in petrochemical field, low pressure boiler and engine cooling water system.

Application in Concrete
1. Various industrial and civil construction, water conservancy, transportation, ports, municipal and other projects.
2. And precast concrete, reinforced concrete and prestressed concrete.
3. Retarding or super retarding concrete, park or take time long-distance transportation of concrete, self-leveling vibration-free concrete.
4. Concrete, roller compacted concrete, hot climates concrete construction, large cast concrete, concrete to avoid cold joints produced.
5. Preparation of high performance concrete.
6. According to user needs can be formulated to apply special cement, mixed with a variety of mixed materials are concrete stick plus Jing different performance requirements.
C: Sodium Naphthalene Sulfonate Formaldehyde
*It's a chemically synthesized non-air-entrained superplasticizer
* It has strong dispersion effect on cement particles and good use effect of preparing super flowing concrete as well as cast in suit concrete and precast members with early strength and high strengtrained superplasticizer
* It has strong dispersion effect on cement particles and good use effect of preparing super flowing concrete as well as cast in suit concrete and precast members with early strength and high strength requirements , can comprehensively improve various properties of concrete
|construction chemical polycarboxylate superplasticizer|
|Appearance||Brown yellow powder|
|Static slurry fluidity||≥230mm|
Character when used in Concrete:
1.In concrete strength and slump substantially the same time, it can reduce the amount of cement 10-25%.
2.When water-cement ratio unchanged, concrete slump initial raise more than 10cm water reduction rate of up to 15-25%
3. Of concrete significant early strength, enhance the effect, its strength were increased by 20-60%.
4.Improve the workability of concrete, improve the physical and mechanical properties of concrete.
5.Good adaptability to various cement, and other various types of concrete admixtures good compatibility.
6.Particularly suitable for use in the following concrete works: flowing concrete, plastic concrete, steam curing concrete, permeability of concrete, waterproof concrete, nature conservation precast concrete, reinforced and prestressed concrete, high strength and ultra high strength concrete.
7.When the concrete slump loss is large, half an hour slump loss of nearly 40%.
Powder : 0.75%~1.5%
Liquid : 1.5~2.5%
D: Sodium Ligno
*The sodium lignosulfonate is from alkaline paper-making black liquor through concentration filtration and spray drying
*It has good physical and chemical properties such as cohesiveness, dilution, dispersibility, adsorptivity, permeability, surface activity, chemical actiry and bioactivity and so on
Application In Concrete
* Reduce water consumption by 10 to 14,
* To improve the workability of concrete, improve project quality,
* Could slump loss in summer use, generally complex to use with superplasticizer.
