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.
Superplasticizer - an overview | ScienceDirect Topics
Superplasticisers are commonly used in dry-pressed concrete to improve the workability and to enhance the compaction of concrete for increasing density and to improve the surface finish of the concrete product.

Revealing the Mystery of Admixtures: Water-Reducing
Mid-range water-reducing admixtures were developed to increase the slump beyond the range available with regular water reducers without the excessive retardation that had been known to occur. High-range water reducers, commonly called superplasticizers, were developed for high-strength and high-performance concrete applications.
Master Builders Solutions presents new superplasticizer
As a Gold Sponsor at the 18th ERMCO Congress, which is being held in Oslo, Norway, on June 7 and 8, 2018, BASF is presenting its broad portfolio of innova-tive solutions for the ready-mixed concrete industry under the brand name of Master Builders Solutions. At the Congress, users can learn about the benefits of the latest superplasticizer generation.
- 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 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 the difference between superplasticizers and set retards?
- Superplasticizers disperses cement provides plastics with higher initial strength than free concrete with the same W/C ratio. Set retards are adductors that cause delays in the setting time of wet concrete mixes.
- What is a high-performance superplasticizer?
- A high-performance superplasticizer can be prepared by using bio-polymer chitosan as a raw material by chemical performance. This greatly improves the strength of high strength concrete with the presence of silica fume. Hello, I'm Rahul Patil founder of Constructionor.com, I had studied B.E. Civil.
