Concrete Superplasticizer PCE Powder Polycarboxylate Superplasticizer CAS 62601-60-9 HWR-S

Polycarboxylate water-reducing agent PCE powder is a powdery polycarboxylic acid high-performance concrete water-reducing agent produced using a new process. It has excellent comprehensive indicators, good dispersion, high water reduction rate, good adaptability to various cements, and is green and pollution-free.

Polycarboxylate Superplasticizer Abstract:

The preparation method comprises the following steps: adding unsaturated polyether methyl allyl polyoxyethylene ether, hydrogen peroxide and 2-acrylamide tetradecyl sulfonic acid into deionized water to prepare a base solution; dripping a solution A consisting of acrylic acid, methacrylic acid and a chain transfer agent mercaptoacetic acid and an aqueous solution of vitamin C, stirring uniformly, carrying out a free radical polymerization reaction at the room temperature, and regulating the pH value of the reaction system to be 6-7 by using liquid caustic soda after the reaction is ended, thereby obtaining the polycarboxylate superplasticizer. The polycarboxylate superplasticizer obtained by the invention can maintain long-lasting dispersity, has long branched chains, is good in dispersion stability, simple in preparation process and low in energy consumption, can be synthesized at the room temperature and has good economic benefits.

Key Properties:

- Good dispersability
- High water reduction
- Excellent adaptability with kinds of cement
- High flowability in mortar or concrete

How To Use Polycarboxylic Acid Superplasticizer Powder:

1. Use of water-reducing agent in concrete: According to the concrete design requirements, adjust the water amount or sand rate through experiments to achieve the amount of water-reducing agent that meets the requirements for slump, strength, and condensation.
2. Tetrachlorethylene powder is suitable for high-performance concrete, high-strength concrete, and large-flow concrete. In order to make the flow performance of the produced concrete meet the construction requirements, the concrete strength should have a certain surplus coefficient.
3. Perchlorethylene high-efficiency water-reducing agent can be mixed with water-mixed concrete at the same time, and the effect of water-mixed concrete will be better.

 
Polycarboxylate Superplasticizer Product Features:

1. High water reduction rate: it can make the water reduction rate reach more than 25%, and greatly improve the fluidity
under the condition of the same amount of water added to the concrete;
2. high slump resistance: in the spray drying process, the carboxylic group will cause more or less damage to the
traditional polycarboxylate superplasticizer. So as to greatly reduce the slump retention performance after the liquid is
ransformed into solid. Sp-409 is manufactured by a special process, so that the carboxylic acid group is not damaged
in the powder manufacturing process, so as to retain the slump retention of the original liquid mother liquor.
3. Good solubility and fast dissolution rate: due to its uniform particles and large specific surface area. Therefore, it can
be dissolved quickly in the process of water dissolution. And there are no obvious impurities after dissolution.

Scope of Application:

1. Suitable for long-distance construction projects type pumping concrete.
2. Suitable for compounding normal concrete,high-performance concrete,high-strength concrete and ultra-high strength concrete.
3. Suitable for impervious,antifreezed and high durability concrete.
4. Suitable for high-performance and high flowing concrete,self-leveling concrete,fair-faced concrete and SCC(self compact concrete).
5. Suitable for high dosage of mineral powder type concrete.
6. Suitable for mass concrete that used in expressway,railway,bridge,tunnel,water conservancy projects,ports,wharf,underground etc.
