Amphoteric polycarboxylate superplasticizers with enhanced
The specimens were prepared under a mass ratio of 3:1 for standard sand to cement, a superplasticizer dosage of 0.15 wt% (by weight of cement) by adjusting the water amount to achieve the fluidity of 180 ± 5 mm. The mold was removed and maintained in a standard curing box at 20 ± 5 °C after 24 h.
Raw materials for superplasticizers
Raw materials for superplasticizers. Superplasticizers are used extensively in larger projects where reinforcing steel requires high workability, for precast concrete and on site where the large water reduction capability provides very early strength concrete with improved durability. Clariant is one of the world's leading suppliers of

SUPERPLASTICIZERS. Superplasticizers are chemical additives that plasticize concrete and plaster mixes. Their main function is to reduce the amount of mixing water. These chemicals are added to the mix in order to improve its rheological properties, which directly translates into increased stability of the finished products.
Structural characterization of a third-generation commercial
In this case, a third‐generation (polycarboxylate based) superplasticizer was studied at various experimental conditions (excitation lines: 325, 445, 532, 633, 785, and 1064 nm; and pH values...
Advances in Admixtures| Concrete Construction Magazine
An article in the March 1990 issue described “third generation” superplasticizers that maintained normal setting properties and still produced a low-water-cement-ratio concrete that would retain a high slump for an extended time.
- What is a superplasticizer used for?
- Superplasticizers are used in production of concrete admixtures to enable high levels of workability, and water reductions of up to 40%.
- What are the different types of superplasticizers?
- According to their dispersing functionality and action mode, one distinguishes two classes of superplasticizers: Steric effects: Polycarboxylates - ether (PCE) synthetic polymers bearing lateral chains (third generation).
- 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 shaliplast® PCE 300?
- ShaliPlast® PCE 300 is a third generation Poly-Carboxylated Ether based super-plasticizer for concrete and mortar. High Performance Poly-Carboxylated Ether Based Superplasticiser ShaliPlast® PCE 400 is a third generation Poly-Carboxylated Ether based super-plasticizer for concrete and mortar
- What is shaliplast ® PCE 400?
- ShaliPlast® PCE 400 is a third generation Poly-Carboxylated Ether based super-plasticizer for concrete and mortar Poly-Carboxylated Ether Based Admixture for Zero Slump and Slip-Form Concrete ShaliPlast ® ZS is a poly-carboxylated ether-based superplasticizer which has been specifically designed for low to zero slump concrete.
