DTDP plasticizer Jayflex DTDP plasticizer is the highest-molecular-weight phthalate plasticizer, providing greater performance at high temperatures. It is the preferred plasticizer for automotive cable applications and THHN/NMB electrical wire insulation. Learn more Linear plasticizers
Selection of Superplasticizers for High-Performance Concrete
Selection of Superplasticizers for High-Performance Concrete Home / Concrete Technology / Concrete Admixtures Reading time: 10 minutes Superplasticizers are used to fluidify the concrete in the field. Most of the superplasticizers helped to maintain high slump values for a time of 30 to 45 minutes.
NUCLEAR POWER PLANT CONCRETE STRUCTURES - Stanford University
High Strength / High Performance Concrete HPC was used in the construction of Civaux-2 NPP of France. This HPC was characterized by its low cement content (266 kg/m3) and water content (161 liter/m3), as well as by the use of silica fume and calcareous fillers (Larrard 1990).

- 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 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 is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizer (PCE), the third generation of high-performance superplasticizer, follows the development of ordinary plasticizers and superplasticizers. It significantly reduces water content while enhancing concrete's workability, strength, and durability.
- What is a superplasticizer (PC)?
- PC consists of a family of products with different chemical structures and acts as a single unit. Generally, all superplasticizers are synthetic polymers, and each type possesses varying characteristics including the percentage of water reduction, retardation, molecular weight, chemical substitution, and cost.
- Which superplasticizer admixture is better?
- Based on the findings, out of three superplasticizers, PC—based admixture showed a better improvement in strength aspects compared to other mix. Compressive strength of UHPC (a) SNF admixture (b) SMF admixture (c) PC admixture
- What is the maximum tensile strength of a superplasticizer?
- The maximum split tensile strength at 28 days of testing for all cases was found to be 29.09 MPa—SNF based, 30.72 MPa—SMF based, and 31.23 MPa—PC-based admixture, respectively, at 1.5% of dosage (Fig. 6). Therefore, the effect of superplasticizers mainly influences the workability of concrete rather mechanical properties.
