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 & Viscosity Modifier in Concrete Countertop
It is used to reduce the slump of concrete, essentially performing the opposite of a high range water reducer (superplasticizer). It also helps prevent segregation in aggregate-based mixes. It is available in 8-oz bags, which is enough for dozens of average concrete countertop projects. VMA should not need to be used for every project, as
Selection of Superplasticizers for High-Performance Concrete
The naphthalene superplasticizers are marketed with a solid content from 40 to 42 percent. The melamine superplasticizers are marketed for a solid content of 22 to 30 %. New melamine superplasticizers are said to have solid content of 40 percent. The experience show that the efficiency of the superplasticizers depends on the following parameters:
Conplast Sp 500 Concrete Superplasticizer Admixture
Compatibility : Can be used with all types of cements excepthigh alumina cement. Conplast SP500 is compatible withother types of Fosroc admixtures when added separately tothe mix. Site trials should be carried out to optimise dosages. Workability : Can be used to produce flowing concrete thatrequires no compaction.

- What is a superplasticizer in concrete?
- Superplasticizers allow a 30% or more reduction in water content. It is chemical admixtures that are added to the concrete to improve their flowing ability, they help to reduce the amount of water in the concrete and to improve the strength and durability of concretes. They achieve a reduction in water content without loss of workability.
- 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 a high range concrete superplasticizer?
- High range concrete superplasticizers have a strong dispersing effect on cement, which can greatly improve the fluidity of the cement mixture and the slump of the concrete, and at the same time greatly reduce the water consumption and significantly improve the workability of the concrete.
- 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 are the benefits of superplasticizers in precast concrete?
- The loss of workability in concrete is slower than that normally produced with superplasticizers. Increased strength at all ages without increasing cement content, which is particularly beneficial in precast concrete.
- What is Kingsun concrete superplasticizer?
- Therefore, Kingsun concrete superplasticizers can be suitable for prefabricate and cast-in-place reinforced concrete in various industrial and civil construction, water conservancy, transportation, port, municipal and other projects. Besides, it can be used for the water-reducing and reinforcing components of various composite admixtures.
