Polycarboxylate Superplasticizers

Beijing Dongke Technologies is one of the most popular manufacturers of polycarboxylate superplasticizers, among other products. Some features of their original product are excellent performance in dispersion and good slump retention, enhanced fluidity, compatibility, and environmental friendliness. The product is applied in a variety of industries, including waterproofing grouting, manufacture of ceramics, motor repair, and base floor grouting. Other traditional applications include the construction of high-speed railways, highways, and concrete. In this write-up, we discuss the basics of polycarboxylate superplasticizers.

What is a superplasticizer?

A superplasticizer also referred to as a high range water reducer, is an additive that is used in the manufacture of high strength concrete. On the other hand, a plasticizer is a chemical compound that is used in the production of cement. The role of superplasticizers is to help lower the water content by 30%, and in some cases, it is more. These additives are used in situations where well-dispersed particle suspension is needed to help improve the quality of suspension in applications like concrete production. When they are added to concrete and mortar, superplasticizers help with the reduction of water to cement content without adversely affecting the usability of the mixture. This helps to enable the production of self-consolidating concrete as well as concrete that performs perfectly.

Meaning of polycarboxylate superplasticizers

Different sorts of substance admixtures are utilized to improve the auxiliary properties of cement, for example, processability, pumpability, hardening properties, mechanical properties, freeze-defrost obstruction, and shrinkage. Also, compound admixtures can be utilized to make and assemble exceptional types of cement, for example, high flow and high-quality concrete, submerged cement, and shotcrete.

The History of polycarboxylate superplasticizers

Polycarboxylate comb polymer (PCE) was established as another kind of cement superplasticizer in the year 1981, which is an achievement in concrete-related technology. The introduction of this technology has made it possible to come up with advanced concrete. For instance, ultra-high-quality cement (UHPC) with a compressive quality of 150 MPa or compacted self-compacting concrete (SCC). Moreover, explicit PCE atoms are intended to give a long slump of at least 2 hours for prepared blended cement without yielding new quality. These models show how significant the contributions of PCE superplasticizers are to present-day concrete-related technology.

Applications of polycarboxylate superplasticizers

Below are a few of the chief applications of polycarboxylate superplasticizers;

  • They are used to pump concrete in situations where the product has to be transported over a long distance.
  • They are also applied in the preparation of different kinds of concrete, including ordinary, high-performance, high-strength, and super-high-strength types. They are used in this situation because they are quite durable and highly impermeable. Other features that aid in this application include the fact that they have high moisture retention elements and are resistant to elements of freeze and thaw.


Beijing Dongke Technologies was established one and a half a decade ago. It is a national high-tech company that specializes in the research and development of construction materials like polycarboxylate superplasticizers. Dongke works with a variety of industries, including the energy, medicine, and construction sectors, and it is based in Beijing and serves clients from different parts of China.
