Superplasticizer
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. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers retard the curing of concrete. [1]
Difference Between Plasticizer and Superplasticizer
The main difference between plasticizers and superplasticizers is that plasticizers can reduce the need for water by 5-15% whereas superplasticizers can reduce the need for water by 30%.

Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers are most widely used additives in plastics. They are generally available as non-volatile, colorless liquids. Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt.

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.
Plasticizer
In the concrete technology, plasticizers and superplasticizers are also called high range water reducers. When added to concrete mixtures, they confer a number of properties including improved workability and strength. The strength of concrete is inversely proportional to the amount of water added, i.e., the water-cement (w/c) ratio.
- What is the difference between a plasticizer and a superplasticizer?
- Plasticizers are also referred to as water reducers. Superplasticizers can also be referred to as high range water reducers. Plasticizers are added 0.1-0.5% by weight of cement. Superplasticizers are added 0.5-0.3% by weight of cement. Plasticizers can reduce the need for water by 5-15%. Superplasticizer can reduce the need for water by 30%.
- What is a superplasticizer admixture?
- Superplasticizer is a water-reducing admixture capable of producing large water reduction or great flowability without causing undue set retardation or entrainment of air in mortar or concrete. Superplasticizers can also be referred to as high range water reducers. Superplasticizers are added 0.5-0.3% by weight of cement.
- What is a superplasticizer in concrete?
- Superplasticizer also refer to as high-range water reducers or retarders are a water-reducing admixtures for concrete, which are added in order to reduce the water content in a mixture or to slow setting rate of concrete while retaining the flowing properties of a concrete mixture.
- What are superplasticizers used for?
- Superplasticizers are added 0.5-0.3% by weight of cement. Superplasticizer can reduce the need for water by 30%. Superplasticizers are used to further increase the water requirement for concrete mixture, increasing the strength and durability of concrete. The commonly used Superplasticizers are SMF, SNF and PCE.
- What are the different types of superplasticizers?
- The commonly used Superplasticizers are SMF, SNF and PCE. Any substance added to a polymer material that can increase the plasticity of the polymer material that can increase the plasticity of the polymer is referred to as a plasticizer.
- How can superplasticizers reduce water in a concrete mixture?
- Segregation of different particles in a concrete mixture can also be avoided by adding superplasticizers. Superplasticizers are improved chemical compounds when compared to plasticizers. The reduction of water can be around 30%. We can add 0.5-3% of superplasticizers (by weight of cement) to a concrete mixture.
