Polycarboxylate Superplasticizer

Polycarboxylate superplasticizer (PCE) is a new generation of high-performance superplasticizer. It is developed after the common water reducing agent represented by wood calcium and the high-efficiency superplasticizer represented by naphthalene series. At present, PCE is a superplasticizer with the best application prospect and the best comprehensive performance. So it can be widely used in highways, bridges, dams, tunnels, high-rise buildings, and other projects.

As a new type of green concrete admixture, polycarboxylate superplasticizers can be used for high-strength concrete, high-performance concrete, mass concrete and high-quality fluid plastic concrete. And PCE has the features of water reduction, slump retention, reinforcement, shrinkage resistance, and environmental protection. In addition, it can also be compounded with various admixtures into multifunctional concrete admixtures, such as pumping agent, early strength agent, impermeable waterproofing agent, retarder, etc.

Polycarboxylate superplasticizers have become one of the most important superplasticizers in the concrete admixture market due to its outstanding advantages, such as high water-reducing rate, good effect, good adaptability with cement, and slump protection performance. With the construction of large-scale infrastructure such as nuclear power, water conservancy, bridges, tunnels, etc., especially the implementation of planning and railway passenger dedicated line network projects, the market demand for PCE superplasticizers have been showing a continuous growth trend.

Kingsun Polycarboxylate Superplasticizer for Sale

As a leading manufacturer of PCE based admixture in China, Kingsun can provide three types of PCE based superplasticizers for all the customers. They are PCE (High Water Reduction) and PCE (High Slump Retention), and PCE powder. Although their appearance and specifications are different, the water reduction rate of polycarboxylate based superplasticizer can reach more than 25%. The following is their detailed introduction:

  • PCE powder is a new generation of environmentally friendly high-efficiency water reducing agent for mortar based on new synthesis technology. Its main component is polycarboxylate, which is a fluid powder made by special drying technology. Its comprehensive indicators are excellent, green and pollution-free, and it is a high-performance environmentally friendly product. The main features of PCE powder: good dispersibility, high water reduction rate, good adaptability with various cements.
  • PCE (High Water Reduction) can greatly reduce the water consumption of cement, increase the fluidity of concrete, and improve the crack resistance of cured cement. It can be widely used in non-shrinkage grouting, repair mortar, etc.
  • PCE (High Slump Retention) keeps the slump of concrete well. It can prolong the slump retention time of concrete. What’s more, it also shows great performance in hot environments.

Main Applications
  • PCE superplasticizer is suitable for pumping concrete for long-distance transportation.
  • It is used to prepare ordinary concrete, high-performance concrete, high strength concrete, and super high strength concrete.
  • Formulate durable concrete with impermeability, high moisture retention, and freeze-thaw resistance requirements.
  • This product is suitable for the preparation of high fluidity concrete, self-leveling concrete, fair-faced concrete, and vibration-free self-compacting concrete.
  • It is suitable to configure various concretes with high fly ash and mineral powder.
PCE Advantages
PCE superplasticizer imparts excellent workability, good strength development, and excellent durability to concrete.
  • Low dosage and high water reduction rate. The water reduction rate of polycarboxylate admixture
    can reach 25~45%, which is suitable for high-performance concrete production;
  • The loss is small while the slump is light. In the case of ready-mixed concrete for about 2 hours, the slump loss will be controlled within 15% by the application of it, which is beneficial to pumping construction and the long-distance transportation of commercial concrete.
  • After adding the polycarboxylic acid-based water reducing agent, the concrete has good workability. In the high slump, the concrete does not significantly separate or bleed, and the color of the concrete is uniform. It is conducive to the preparation of high-flow concrete and self-leveling concrete.
  • After the use of polycarboxylate water reducer, concrete shrinkage is relatively low, which can reduce the degree of concrete shrinkage and improve the durability and stability of concrete.
  • The polycarboxylate admixture has the characteristics of green environmental protection and non-toxic and harmless. It is conducive to the sustainable and healthy development of the construction industry.
  • It has good compatibility with various types of cement, good slump retention performance of concrete, and prolonged concrete construction time.
  • More slag or fly ash can be used instead of cement to reduce costs by adding polycarboxylate concrete admixture.
Instructions for Use

 

  • The recommended dosage range of polycarboxylate superplasticizer is 0.5%-1.6%, and the dosage range can be adjusted appropriately for special cement or aggregate.
  • It can be mixed into the metered water and added to the concrete mixer at the same time with water. In order to achieve a good water reduction effect, we recommend that the mixing time is at least 150s.
  • When using this product for the first time or changing the cement type, the necessary trial mixing test should be carried out according to the site raw materials and construction conditions, and the mixing amount and construction mixing ratio should be determined according to the test results to ensure the quality of the concrete.
  • Due to the high water reduction rate of PCE superplasticizer, its concrete slump is very sensitive to the water consumption, and the water consumption and dosage must be strictly controlled during use.
  • PCE should not be mixed with naphthalene, melamine, amino and other water reducing agents, otherwise the performance index will be significantly reduced.
Development of PCE
  1. High performance. Due to the needs of the modern construction industry and concrete engineering, more stringent requirements are put forward on concrete, such as higher fluidity, a higher degree of compatibility with other additives, a higher degree of environmental protection, etc. High-performance concrete mainly relies on high-performance admixtures. Therefore, it is necessary to further improve the research technology of high-performance water-reducing agents to make them more optimized and economical, thereby improving the performance of concrete.
  2. Low cost. In order to improve the utilization rate of PCE based superplasticizer in the modern construction industry, reduce costs is an effective method. Realize the reuse of solid waste resources is a good way to reduce costs. Fundamentally reduce costs, save resources, and improve the economic benefits of polycarboxylate water reducer.
  3. Functional composite type. The compound type water reducer means that the water reducer has the ability to improve the various indicators of concrete, and it has stronger performance in improving a specific index of the concrete, which can not only exert the advantages of the water reducer, It can also improve the performance indicators of concrete and increase the selection range of water-reducing agents. The entire construction engineering industry has a great demand for composite water-reducing agents.
