Retarding Admixture - an overview | ScienceDirect Topics
These admixtures are often referred to as super-plasticizers and can provide significant benefits for producing flowing concrete in hot weather concrete conditions (ACI 305R-99). Most super-plasticizers are synthetic water-soluble polymers such as sulfonated naphthalene formaldehyde (SNF), sulfonated naphthalene polymer (SNP), modified sugar

Setting Time of Superplasticizer Concrete. - ResearchGate
The concrete were prepared for two different cement contents of 350kg/m 3 and 450kg/m 3 mixed at W/C ratio of 0.55. Due to high demand of mixing water the super plasticizer at 2.5% and 3% for...
Behaviour of Normal Concrete Using Superplasticizer under
Different dosages of superplasticizer were used in different batches of all 95 specimens, and cured under different curing conditions and then tested for compressive and tensile strengths following...
- 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 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 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.
