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.
Comparative Studies of High Strength Self
The experimental outcomes revealed that third generation superplasticizers induce more efficient dispersion defined by superior consistency levels and increased hardened strengths. Content...
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.

It must be stated, though, that making good quality SCC without these latest generation superplasticizers is almost impossible. Limited experience with these chemicals indicates that they work well at low water to cement ratios, and exhibit fewer compatibility problems compared to SNF.

- 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 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.
- 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).
- Which polyglycols are used in synthesis of PCE -superplasticizers?
- Clariant is one of the world's leading suppliers of polyglycols used in the synthesis of PCE -superplasticizers (3rd generation superplasticizers). Our Polyglykol M-types meet all requirements for esterification e.g. with methacrylic acid, acrylic acid and pre-polymerized (meth-)acrylates.
- What are alternative macromonomers for superplasticizers?
- Common alternative macromonomers for superplasticizers are Polyglycol methallyl ethers (Polyglykol ML) which can be directly polymerized in water. Therefore, this synthesis route saves cost and time and reduces complexity as there is no need for the esterification of a methoxy polyglycol before the polymerization process.
- Are plasticizers lignosulphonates?
- Traditional plasticizers are lignosulphonates as their sodium salts. Super plasticizers are synthetic polymers. Compounds used as superplasticizers include (1) sulfonated naphthalene formaldehyde condensate, sulfonated melamine formaldehyde condensate, acetone formaldehyde condensate and (2) polycarboxylates ethers.
