Raw materials for superplasticizers
Superplasticizers are used extensively in larger projects where reinforcing steel requires high workability, for precast concrete and on site where the large water reduction capability provides very early strength concrete with improved durability.
Comparative Studies of High Strength Self-Compacting
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.
Superplasticizer: Types, Advantages & Disadvantages
Superplasticizers (SPs) are also known as high- range water reducers that are additive used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow a 30% or more reduction in water content.

- 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 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 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 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).
- 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.
