Frontiers | Synthesis of Modified Polycarboxylate and Its
Polycarboxylate has functions such as slump protection, coagulation control, and shrinkage reduction. By adding polycarboxylate, the force between Portland cement particles and the physicochemical properties of their solid–liquid interface are changed, thus affecting the flowability of cement paste ( Andersen et al., 1987; LI et al., 2005 ).

polycarboxylate superplasticizer with high water retention. The performance test results show that the product has high water-reducing ratio and better workability when applied to concrete, which can effectively retain the moisture in concrete and ensure the stability of concrete fluidity. 1.

Preparation of polycarboxylate-based superplasticizer and its
A series of polycarboxylate-based superplasticizers (PCs) with different structures were synthesized and the effects of chemical structure on zeta potential and rheological property of cement paste were studied. Residual monomers in each sample of PCs were quantitatively determined. The property of the polymers in cement was tested by micro-electrophoresis apparatus and R/S rheometer. Results
- What is polycarboxylate superplasticizer?
- 1. Introduction The polycarboxylate superplasticizer is characterized by low dosage requirements, a high water-reducing rate, excellent slump retention performance, and strong designability and environmental friendliness during the production process, making them the most widely used admixture in modern concrete , , .
- Does polycarboxylate superplasticizer affect rheological properties of cement paste?
- Molecular structures of polycarboxylate (PCE) superplasticizer significantly affect the rheological properties of cement paste. Consequently, we employed self-synthesized PCE copolymers with different carboxylic densities to investigate their influence on the rheological behavior of cement paste.
- Can a polycarboxylate superplasticizer be used for 70 flow-carbon cement?
- This innovation could broaden the range of applications for 70 flow-carbon cement applications (Shu et al., 2016; Sabzi et al., 2024; Wang et al., 2024). Polycarboxylate Superplasticizers In 1981, a PCE concrete water reduction agent was developed.
- Can polycarboxylate superplasticizer improve adsorption capacity?
- According to the literatures [14, 15], the introduction of silane to polycarboxylate superplasticizer can improve its adsorption capacity to the surface of cement, so as to improve its water reduction performance. However, the adsorption of the superplasticizer on cement grains will affect its migrating amount in the substrate.
- Which chain transfer agent is used in polycarboxylate superplasticizer?
- The selected chain transfer agent is 3-mercaptopropionic acid. Under conditions where the acid-ether ratio is 4.0:1, the reflection temperature is 35°C, the sulfonic acid content is 16.0%, and the initiator dosage is 1.0%, with all other reaction conditions held constant, polycarboxylate superplasticizer were synthesized.
- What is silane-modified polycarboxylate superplasticizer (s/AA-hpeg)?
- 2.2. Synthesis of the silane-modified polycarboxylate superplasticizer The silane-modified polycarboxylate superplasticizer (S/AA-HPEG) was synthesized through radical copolymerization with methacryloyloxypropyltrimethoxysilane (S), isobutylene polyvinyl ether (HPEG) and acrylic acid (AA).
