Plasticizer vs. Superplasticizer — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on September 27, 2023
Plasticizer is an additive that increases the plasticity or fluidity of a material, while Superplasticizer is a high-range water reducer used in concrete mixtures to improve workability without increasing water content.

Key Differences
Plasticizer and Superplasticizer are both additives used in construction, but they serve different functions and are used in varying quantities. A Plasticizer generally increases the plasticity or flexibility of a material, making it more malleable and easier to work with. On the other hand, Superplasticizer, as its name suggests, provides superior workability improvement, especially in concrete mixtures.
In the context of concrete, while both Plasticizer and Superplasticizer improve workability, Superplasticizers are known to achieve a high degree of water reduction without negatively impacting the strength of the concrete. Plasticizers, however, offer a moderate increase in workability with some water reduction.
The mechanism of action also differs. Plasticizers typically work by spacing out the cement particles, thereby reducing friction. Superplasticizers, however, are chemically more active and can disperse cement particles more effectively, achieving higher water reduction.

Plasticizer
A plasticizer (UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, or to decrease friction during its handling in manufacture. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the raw material during fabrication, or to meet the demands of the end product's application.
Superplasticizer
Superplasticizers (SP's), 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.
Plasticizer
Any of various substances added to plastics or other materials to make or keep them soft or pliable.
Superplasticizer
