Superplasticizers
Superplasticizers High-level water reduction products can be used in high strength concrete, pumpability, self-consolidating concrete, low permeability, low water absorption concrete and low shrinkage application.

Recommended uses of MasterGlenium 3030 concrete superplasticizer: Concrete where high flowability, high-early and ultimate strengths and increased durability are needed Self-consolidating concrete Concrete where normal, mid-range, or high-range water-reduction is desired Concrete where normal setting times are required
Superplasticizer in Concrete - Concrete Forms and Shoring
There are three main ways that superplasticizers can be used: to create flowing and self-leveling concrete without increasing water or cement and without sacrificing strength; to produce workable, high-strength concrete by reducing water and the water to cement ratio; or to save cement by reducing both the water and cement contents while
SP-354: Superplasticizers and Other Chemical Admixtures
Ottawa, ON, Canada, on the use of superplasticizers in concrete. Selected papers from the conference were published as ACI SP-62. In 1981, CANMET, again in association with ACI, sponsored a second 3-day international conference in Ottawa on the use of the superplasticizers in concrete. Proceedings of the conference were published as ACI SP-68.
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.
- 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.
- 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.
- 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.
- Does superplasticizer affect workability and properties of self-compacting concrete (SCC)?
- This research examined the effect of superplasticizer on workability and properties of self-compacting concrete (SCC). Three types of superplasticizers Conplast SP 561, Conplast SP 430 and Conplast SP 264 at different percentages (0, 10, 20 and 30%) with the same water cement ratio of 0.3, with M30 grade of concrete.
- When did superplasticizers come out in concrete?
- In May 1978, the Canada Centre for Mineral and Energy Technology (CANMET), in association with the American Concrete Institute (ACI) sponsored a 3-day conference in Ottawa, ON, Canada, on the use of superplasticizers in concrete. Selected papers from the conference were published as ACI SP-62.
- 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.
