Polycarboxylate Superplasticizer (PCE) For Concrete
Polycarboxylate superplasticizer (PCE), also known as polycarboxylate ether superplasticizer, is a new generation of high-performance concrete admixture. It is a water reducing agent with excellent performance that integrates water reduction, slump protection, reinforcement, shrinkage and environmental protection.
Polycarboxylate Superplasticizers - Concrete Construction
Very often, a superplasticizer will be formulated with a blend of two or more PCEs to achieve a combined performance of both early strength and long slump life. Researchers will continue to actively manipulate PCE polymer structure to meet the ever changing material and construction requirements.
Superplasticizer
Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers retard the curing of concrete. [1]

- What is PCE superplasticizer?
- PCE superplasticizer is a high-performance water reducing agent that integrates many functions such as high water reduction, high collapse retention, reinforcement, shrinkage, and environmental protection. It is also an ideal admixture for preparing high-strength and high-performance concrete.
- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizer (PCE), the third generation of high-performance superplasticizer, follows the development of ordinary plasticizers and superplasticizers. It significantly reduces water content while enhancing concrete's workability, strength, and durability.
- What is a superplasticizer used for?
- Superplasticizers (SPs), also known as high range water reducers, are additives used for making high strength concrete or to place self-compacting concrete. Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.
- What is the difference between a plasticizer and a superplasticizer?
- Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers also retard the setting and hardening of concrete.
- What is a polycarboxylate ether superplasticizer?
- The polycarboxylate ether superplasticizer is an additive commonly used in concrete engineering and has a wide range of applications. The PCE based admixture can significantly reduce the amount of cement and improve the fluidity and pumpability of concrete while ensuring the strength and durability of concrete.
- Who invented PCE superplasticizers?
- In this article, at first Dr. Tsuyoshi Hirata - the main inventor of PCE superplasticizers – reports on the history behind the invention of PCEs. Next, a critical overview of recent innovations in PCE technology with an emphasis on novel polycarboxylate chemistries is presented.
