40 years of PCE superplasticizers - History, current
2025 marks the 40th year since polycarboxylate superplasticizers (PCEs) have been invented by Nippon Shokubai company in Japan. This invention clearly represents a major breakthrough and...
Adsorbed Conformations of PCE Superplasticizers in Cement Pore
The conformations of polycarboxylate ether (PCE) type superplasticizer polymers adsorbed on the surface of MgO in cement pore solution are simulated by molecular dynamics (MD). Three types of PCEs
Effect of polycarboxylate ether superplasticizer (PCE) on dynamic yield
All mixes have a water-to-cement ratio (W/C) of 0.4 by mass. As a parameter, the amount of PCE superplaticizer addition varies from 0, 0.05, 0.1, 0.15, 0.2, 0.25 to 0.3% by mass of cement. The polycarboxylate ether superplasticizer (PCE) used in this study is a commercial product commonly used in European market (MasterGlenium 51).
Project Report On Polycarboxylate Ether Superplasticizer (Pce)
Polycarboxylate ether superplasticizer (PCE) or just polycarboxylate (PC), work differently from sulfonate-based superplasticizers, giving cement dispersion by steric stabilisation, instead of electrostatic repulsion. This form of dispersion is more powerful in its effect and gives improved workability retention to the cementitious mix.

- Does Polycarboxylate ether-based superplasticizer affect workability and strength of concrete?
- Commonly used high range water reducer admixture, the polycarboxylate ether-based (PCE) superplasticizer has been used to investigate its influence on workability and strength of concrete by measuring slump and ultrasonic pulse velocity as well as crushing strength. The cement of grade 43 has been used in this work.
- What is Polycarboxylate ether superplasticizer (PCE)?
- The polycarboxylate ether superplasticizer (PCE) used in this study is a commercial product commonly used in the market. It is free of chloride and has the sulphnic groups of polymer chain. The molecular weight is 2400 g/mol. The solid content of PCE surfactants is 30% over the total mass in liquid form.
- 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.
- Does Polycarboxylate ether surperplasticizer improve thixotropy and flocculation state?
- Polycarboxylate ether surperplasticizer (PCE) has been commonly used and studied to enhance flowability of cementitious materials. However, the effect of PCE addition on thixotropy and flocculation state has not gained enough attention. In this study, Focused Beam Reflectance Measurement (FBRM)-rheometer is coupled.
- Are Polycarboxylate ether comb-copolymers a water reducing agent?
- Hypothesis: Polycarboxylate ether (PCE) comb-copolymers are widely used as water reducing agents in the concrete industry while maintaining a high fluidity via the polymer adsorption to the cement particles.
- Can PCE copolymer chains be controlled?
- Controlling the PCE copolymer chains could eters. This work may drive more researchers to exploit controlled and effect of superplasticizers for better performance. ‘SmartCast’. This project has received funding from the European 693755).
