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.

- Which superplasticizer is best for precast concrete?
- In this way, the water content can be reduced without affecting the material's usability. Sulfonated melamine formaldehyde condensates are normally preferred superplasticizers within the precast concrete domain because they do not diffuse the cement setting. Sulphonated Naphthalene Formaldehyde is a high scale water reducer superplasticizer.
- 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.
- How do plasticizers and water reducers affect concrete strength?
- Since the heat of hydration of mass concrete goes down when the cement weight goes down, plasticizers can do this. Plasticizers and water reducers are chemical admixtures used to make concrete more workable. Unless the mixture is “starved” of water, increasing the w/c ratio reduces the concrete’s strength.
- Can superplasticizer dosage predict the compressive strength of self-compacting concrete?
- Independently of the superplasticizer dosage, the found results allow to predict, basing on the measurement of the rheological properties of a self-compacting concrete, its compressive strength. 4. Conclusion
- What are plasticizers & water reducers?
- Plasticizers and water reducers are chemical admixtures used to make concrete more workable. Unless the mixture is “starved” of water, increasing the w/c ratio reduces the concrete’s strength. An increase in durability is achieved by decreasing the water content (without “starving” the concrete).
- What is a superplasticizer in concrete?
- Superplasticizers permit 30% or more reductions in water content. It is chemical mixings that are added to the concrete to develop its flowing capacity, they assist to minimise the quantity of water in the concrete and enhancing the durability and strength of concrete.
