The current work investigates the fluidity and the loss of the flow rate of cement paste and mortar over time, as well as the pore structure and compressive strength of concrete and mortar in the presence of functional polycarboxylic acid high-performance water-reducing agents.

The paper deals with the effectiveness of an innovative phosphonate-based superplasticizer (PNH) for ready mixed concrete. Concrete specimens were manufactured by considering a constant initial workability, equal to 220 mm slump at the end of the mixing procedure.
Effect of Functional Superplasticizers on Concrete Strength and Pore
Because superplasticizer acts as a water-reducing agent, it can reduce up to 30% of the water content in concrete, the strength of the concrete increased after it was added (Xun et al., 2025)....

Scheme of plasticizer and superplasticizer types, influence factors and changes caused in concrete-based composites. A group of compounds providing further reduction in the water/cement ratio of around 25% is called superplasticizers [ 38, 39, 40 ].
- What are the different types of superplasticizers used in concrete?
- With the gradual enrichment of the types of concrete, the types of superplasticizers have also increased, and naphthalene superplasticizers and polycarboxylic acid superplasticizers are beginning to be widely used in concrete [27, 28].
- Do superplasticizers improve the fluidity of concrete?
- 5. Conclusions Superplasticizers are chemical additives that can significantly improve the fluidity of concrete. They work by reducing the surface tension between cement particles and water, thereby reducing the amount of water required to improve the workability of concrete.
- Are polyacrylate-type superplasticizers compatible with other chemical admixtures?
- Polyacrylate-type superplasticizers have high-efficiency water-reduction properties, improve concrete microstructure, and are more compatible with different types of cement, but they have problems with compatibility with other chemical admixtures .
- 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.
- Does PCE superplasticizer adsorb in concrete?
- The adsorption of PCE superplasticizer in a concrete mix was found to be higher than in a cement paste mixed at 700 rpm with identical mixing time, W/C and dosage. However, the relative differences of adsorbed masses of the different PCEs measured in the cement paste correlated with the results from concrete.
- What are inorganic superplasticizers?
- Inorganic superplasticizers contain inorganic salts as the major components, including silicate, phosphate, borate, etc. Inorganic superplasticizers are used to increase the fluidity of concrete while reducing water consumption by modifying the composition and structure of cement and reducing its degree of gelatinization.
