Effectiveness Assessment of Superplasticizer Admixtures: Case
The use of superplasticizers in concrete production has become a common practice, especially when a high fluidity is required. On the other hand, the risk of segregation and the stability of...

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
Use of Water Reducers, Retarders, and Superplasticizer
There are four types of superplasticizers: sulfonated melamine, sulfonated naphthalene, modified lignosulfonates and a combination of high dosages of water reducing and accelerating admixtures. Commonly used are melamine based and naphthalene based superplasticizers.
Superplasticizer - an overview | ScienceDirect Topics
ASTM C 494 was modified to include high-range water-reducing admixtures in the edition published in July 1980. The admixtures were designated Type F water-reducing, high-range admixtures and Type G water-reducing, high-range, and retarding admixtures. Effect of Superplasticizers on Concrete Properties.

- Does superplasticizer admixture affect concrete quality?
- The experiments were classified into two phases: the first phase focused on the effects of superplasticizer admixture on workability and compressive strength, and the second phase determined the influence of superplasticizer admixture on concrete quality by reducing the amount of mixing water.
- Is superplasticizer a good choice for hardened concrete?
- The experiment program included tests on workability, slump test, and flow table. For hardened concrete’s compressive strength test, we compared the properties of superplasticizer-based concrete with those of concrete without superplasticizer. The superplasticizer led to a significant water reduction but maintained workability.
- Does superplasticizer admixture improve workability and compressive strength?
- Results showed that the addition of superplasticizer admixture improved workability and compressive strength. The experiment program included tests on workability, slump test, and flow table.
- Can superplasticizers improve self-compacting concrete workability?
- Self-compacting concrete workability is usually ensured by the addition of superplasticizers in the mixture. The effects of some properties of superplasticizers have been investigated by many researchers.
- Is superplasticizer based concrete good for compressive strength test?
- For hardened concrete’s compressive strength test, we compared the properties of superplasticizer-based concrete with those of concrete without superplasticizer. The superplasticizer led to a significant water reduction but maintained workability. Content may be subject to copyright.
- What is a superplasticizer in concrete?
- A superplasticizer is an admixture properties of a concrete mixture. The use of a and hardened states. In the fresh state, use of a content of concrete.
