Polycarboxylate Superplasticizers - Concrete Construction
Very often, a superplasticizer will be formulated with a blend of two or more PCEs to achieve a combined performance of both early strength and long slump life. Researchers will continue to actively manipulate PCE polymer structure to meet the ever changing material and construction requirements.
Progresses in Synthesis of Polycarboxylate Superplasticizer
Polycarboxylate superplasticizer (PCE) was synthesized by unsaturated monomers of carboxylic acid, alkane macromonomers of long chains, and others. It was an excellent cement dispersant which would make great performance in concrete [ 1 ].

Polycarboxylate Superplasticizers | Supercizer PCE | Fritz-Pak
Supercizer PCE. Polycarboxylate superplasticizers are a fairly recent development in the concrete admixture industry. This unique blend of water-reducing chemicals provides substantially more benefits than previous superplasticizers. In fact, Fritz-Pak’s Supercizer PCE provides up to 40% water reduction and up to an eight-inch slump reduction
- How are polycarboxylate superplasticizers synthesized?
- In this work, a series of polycarboxylate superplasticizers (PCEs) were synthesized via copolymerization using a novel macromonomer, ethylene–glycol monovinyl polyethylene glycol (EPEG). The molecular structures were modified by varying the side chain length, carboxylate density and integrating sulfonic group.
- What is polycarboxylate superplasticizer (PCE)?
- 1. Introduction Polycarboxylate superplasticizer (PCE) was synthesized by unsaturated monomers of carboxylic acid, alkane macromonomers of long chains, and others. It was an excellent cement dispersant which would make great performance in concrete .
- Which polycarboxylate superplasticizer is used to make a concrete mixture?
- Molecularly modified polycarboxylate superplasticizer comprising of TPEG and AA (1:6 mol ratio, PCE-1) and the synthesized MPEGM with TPEG and AA (0.5:1:6 mol ratio, PCE-2) were prepared through solution radical polymerization. Afterward, concrete mixtures with different dosages (0, 0.1, 0.15, 0.2, 0.25, 0.3 wt%) of PCE-1 and PCE-2 were prepared.
- 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.
- What is the molecular structure of modified polycarboxylate superplasticizer (MPCE)?
- It was shown in Fourier transform infrared spectroscopy (FITR) that the molecular structure of modified polycarboxylate superplasticizer (MPCE) contained sulfonic acid groups, carboxylic acid groups, polyethylene oxide vinyl groups, and other groups and had comb-shaped molecular structure.
- 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.
