Superplasticizer Powder with Concrete Water Reducer Additive Polycarboxylate Superplasticizer Powder PCE
Polycarboxylate Superplasticizer powder (PCE fine Powder) is a new ether polycarboxylate water-reducing mother liquid. By adding a small amount of additives and centrifugal drying spray, it forms high flow powder. It features with uniform particles, low water content, good solubility.
Our PCE fine powder can 100% revert to liquid type PCE.
Compare to liquid type PCE, powder type is easy to transport, storage, and save your cost.

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.
Motar Performance:
1. It is homologous between water-reducing rate of motar and fluidity of cement paste. The more fluidity of cement paste, the more water-reducing rate of motar.
2. Water-reducing rate increases fast and high when the dosage increase. When the dosage is same, the water-reducing rate of PCE powder is 35% higher than that of other superplasticizer in market.
3. Due to the influence from the admixture and sand coarse aggregate, Water-reducing rate in concrete is different from that of motar. When the the admixture and sand coarse aggregate are in favour of the concrete flow, the water-reducing rate of concrete is higher than that of motar.
4. It has antifreezing performance when temperature is above -5ºC. So it can be used in antifreezing concrete.
Features & Benefits:
A. Wide adaptation scope: not only used in cement-based materials, but also gypsum-based materials,strong adaptability to various kinds of organic additives, such as water-soluble polymer, dispersible polymer powders has lttle effect on this product.
B. High water reducing rate:make the mortar water reducing rate of more than 30 %, greatly improving the fluidity of the mortar under the condition of same water content in mortar.
C. Early strength and high strength
D. High durability: Reduce mortar water-cement ratio, improve durability, reduce shrinkage and variations, reduce post-curing mortar shrinkage cracking.
E. Green Environmental Product: does not produce pollution of the environment; in line with ISO14000 International Environmental Management Standard.
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.
