Polycarboxylate Ether (PCE)

As the third-generation high-performance superplasticizer, Polycarboxylate ether superplasticizer is also called PCE superplasticizer. PCE has the characteristics of high water-reducing rate, good slump retention performance, designable molecular structure and environmental protection. It has been applied in a large number of projects, such as railway, highway, municipal, hydropower and other engineering fields.

Why Do We Use Polycarboxylate Ether Superplasticizers

With the development of the economy and the diversification of infrastructure projects, people have begun to put forward higher requirements for the performance of polycarboxylate ether superplasticizers. At the same time, due to the poor quality of cement, sand, stone and other materials on the market, polycarboxylate superplasticizers are more sensitive to fluctuations in the quality of concrete raw materials during application, especially in low temperature environments. For example, in winter construction, the phenomenon of stagnation and bleeding of polycarboxylic ether based superplasticizers in concrete is very common, so it is necessary to have higher energy absorption requirements for PCE.

Kingsun polycarboxylate ether superplasticizers have a great strength effect on concrete. It can improve the impermeability, frost resistance and durability of concrete. Polycarboxylate ethers can make concrete has good liquidity and small slump loss at high temperatures. Moreover, it is not necessary to greatly increase the dosage of PCE concrete admixture at low temperatures. Polycarboxylate ether (PCE) is a polymer surfactant. Because of that, it can be used in some paste material to reduce the water content, such as in plaster and ceramics.

Types of Polycarboxylate Ethers for Sale

Compared with other high-range water reducing admixtures, polycarboxylic ether based superplasticizers have many benefits, such as high water-reduction rate with a small dosage, strong dispersion of cement. Besides, strong plasticity is also one of its advantages. It can control the slump loss of concrete mix over time but has little effect on concrete hardening time.

As a professional manufacturer of concrete admixtures in China, Kingsun company can supply three types of polycarboxylate ethers, they are PCE powder, PCE Liquid (high water reduction), PCE Liquid (high slump retention). The following is their detailed introduction:

  • High water reduction PCE liquid can greatly reduce water consumption, increase the fluidity of concrete, and improve the crack resistance of solidified cement. It is widely used in non-shrinkage grouting, repairing mortar, etc. This product can be directly added to concrete or diluted with water before being added to concrete. It is the best choice for fast curing concrete. Because it not only provides early strength to concrete but also can reinforce concrete strength.
  • High slump retention PCE liquid keeps the slump performance of concrete well. It can prolong the slump retention time of concrete. It also exhibits excellent performance in hot environments. This product has wide adaptability to various raw materials. Besides, it has excellent work performance. It can not only fully meet the concrete mixing performance requirements, but also facilitate the concrete operability. The product is easy to use and easily meets the requirements of construction work in remote areas.
  • Polycarboxylate ether powder is a high-performance environmentally friendly product. The product has the characteristics of good dispersibility, high water reduction rate, good adaptability with various cements, green and pollution-free, etc.

Features of Polycarboxylate Based Ether Superplasticizers

  1. High water-reduction rate with a small dosage. The amount of polycarboxylic ether superplasticizer accounts for 0.80%-1.25% of the cementitious material. While the water reduction rate can be as high as 20% – 35%. It can reduce the water cementitious ratio when used with fly ash, so it is suitable for formulating high-performance concrete with high strength.
  2. Good workability for concrete. Even in the case of the high slump, the concrete prepared with PCE superplasticizer will not have obvious segregation and bleeding, and the appearance of the concrete is consistent in color. It is extremely beneficial for the preparation of high-fluidity concrete, self-leveling concrete, self-compacting concrete, and fair-faced concrete. When used to prepare high-grade concrete, the concrete has good workability, good cohesion, and the concrete is easy to mix.
  3. Great adaptability with cementitious material. Polycarboxylate superplasticizer in concrete has good compatibility with different types of cement. There will be no obvious bleeding or segregation of concrete. Because of its high water reduction rate, it can greatly improve the pumpability and durability of concrete.
  4. Prepare high fluidity concrete with small slump loss. Because of the good dispersion ability of polycarboxylate ether-based superplasticizer, it can formulate high fluidity concrete with small slump loss. Adding a small amount of polycarboxylic acid superplasticizer into fly ash can give concrete great fluidity ability. It is suitable for the process requirements for producing commercial concrete.
  5. Suitable for pouring impervious concrete. Polycarboxylate based superplasticizer is suitable for formulating pumping commercial concrete. Because adding it in concrete can give the concrete high fluidity. Then the concrete will be easy to pour and compact. The compactness and strength of concrete can get great improvement. It can enhance the performance of concrete impermeability and crack resistance.
  6. Low-temperature requirements for the construction environment. When the dosage of fly ash is high, the hydration heat of concrete is small. At this time, the plastic protection of polycarboxylate ether-based superplasticizer is obvious. It is suitable for the preparation of large volume concrete and summer construction. As for winter construction, polycarboxylate ethers can reduce the water cementitious ratio of concrete. It can increase the cohesion and the early frost resistance of concrete.
  7. Environmental protection. Polycarboxylate ethers have very low alkali content, chloride ion content, sodium sulfate content, and formaldehyde content, and does not pollute the natural environment during the production process. It meets the ISO14000 environmental protection management national standard and is conducive to sustainable development.
Main Application of Polycarboxylate Ether

Polycarboxylate ether can be widely used in railway, highway, municipal, hydropower and other engineering fields. And it is mainly suitable for the following types of concrete:

  • It is suitable for the production of cast-in-place concrete, prestressed concrete and prefabricated concrete components, especially high-grade concrete.
  • It has good performance for concrete with special requirements such as waterproof, impermeability, frost resistance, erosion resistance and wear resistance.
  • For high-strength concrete of C80 and above, PCE can achieve technical and economic effects that other water-reducing agents cannot achieve.
How to Use PCE
  1. The polycarboxylate admixture can be directly added to the concrete as a stock solution, or it can be formulated into a solution of a certain concentration.
  2. Do not mix with naphthalene superplasticizer. Before using the polycarboxylate water reducer, the mixer using the naphthalene water reducer must be rinsed, otherwise the water reducing effect may not be good.
  3. Its dosage is 0.4% to 2.5% of the total weight of the cementitious material, and the commonly used amount of PCE is 0.8% to 1.5%. So before using PCE, we need to test the concrete to get the best dosage.
  4. PCE series superplasticizers have good adaptability to most types of cement, but individual types of cement may have low water reduction rate and large slump loss. In addition, the fineness and storage time of cement may also affect the use of polycarboxylate ether superplasticizers. At this time, it is recommended to solve this problem by appropriately increasing the dosage or combining with other retarding ingredients.
  5. Due to the high water-reducing rate of polycarboxylate superplasticizers, the slump is highly sensitive to water consumption, so we must strictly control the water consumption during use.
