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.
Concrete Superplasticizers Market by Type, by Application
Polycarboxylates are the third generation superplasticizers that revolutionized the market with their capability to reduce water to cement ratio by 40.0% even at low dosage rates. Compared to...
EPSILONE I 21 : 3rd generation high-range superplasticizers
High performance concrete hyperplasticizer. EPSILONE I 21 is a highly effective synthetic polymer based additive which performs extremely well with Portland cement of various types specifically designed to produce concrete with low water binder ratio and excellent workability.
What Are the Key Features of Polycarboxylate Superplasticizer
PCE superplasticizer is a third-generation concrete product with specific properties that make it ideal for construction purposes. These properties include high water-reduction rate, high strength and compactness, low viscosity, easy operation, strong self-leveling, and environmental friendliness.
Superplasticizer
Superplasticizers ( SPs ), also known as high range water reducers, are additives used in making high strength concrete. 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.
- What is a superplasticizer?
- Our premium superplasticizers are designed to significantly improve the workability and durability of your concrete mixes. By reducing water content without compromising strength, these additives ensure optimal flowability and ease of placement, making them ideal for high-performance concrete applications.
- What are the different types of superplasticizers?
- According to their dispersing functionality and action mode, one distinguishes two classes of superplasticizers: Steric effects: Polycarboxylates - ether (PCE) synthetic polymers bearing lateral chains (third generation).
- What is polycarboxylate superplasticizer?
- Polycarboxylate superplasticizer (PCE), the third generation of high-performance water reducer (water reducing admixture), follows the development of ordinary plasticizers and superplasticizers. It significantly reduces water content while enhancing concrete's workability, strength, and durability.
- 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.
- What is a phosphate superplasticizer?
- Phosphated superplasticizers Phosphated comb polymers holding phosphate functionalities (partly or exclusively) instead of the carboxylate groups commonly found in PCEs have been introduced recently to meet challenges such as increasing the flow speed of concrete or reduced air entrainment .
- Why is hpeg PCE better than other superplasticizers?
- This effect is owed to the higher water demand of the calcined clay. With respect to dispersing effectiveness, among all superplasticizers the HPEG PCE (a commercial precast type PCE) consistently required the lowest dosages and clearly outperformed the other kinds. Fig. 14.
