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.

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
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...
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 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.
- Does superplasticizer improve concrete's compressive strength?
- 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. Keywords: Superplasticizer, compressive strength, slump, workability, admixture.
- Do superplasticizers & retarders increase workability and setting time of concrete?
- Superplasticizers (SP) and retarders are important to enhance the workability and setting time of concrete under hot weather, hence, an experimental investigation was conducted to determine the optimum dosage for the admixtures and to study the effect of over dosage of the mentioned admixtures.
- 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 asuperplasticizing admixture affect concrete properties?
- This study aimed to study the effects of asuperplasticizing admixture, namely, Sikament-NN superplasticizer, on concrete properties, such as workability and compressive strength. Experiments were performed on different concrete mixes with water–cement ratios of 0.50, 0.55, and 0.60.
