Effect of polycarboxylate ether superplasticizer (PCE) on
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).

Process design and optimization of VPEG-PCEs - NASA/ADS
The VPEG type polycarboxylate superplasticizer (PCE-A) was synthesized by using 4-hydroxybutylvinyl polyoxyethylene ether (VPEG) as macromonomer, hydrogen peroxide (H 2 O 2 )reducing agent (sodium formaldehyde sulfoxylateas) as redox system, and thioglycolic acid as the chain transfer agent.
The Effect of Various Superplasticizers on Ultra High
Common examples of superplasticizer compositions include Polynaphthalene Sulfonate (PNS), Polymelamine Sulfonate (PMS) and Polycarboxylate Ether (PCE) based polymers. This study focuses on assessing the impact of various superplasticizers on the performance of UHSC.

- What is a polycarboxylate ether superplasticizer?
- The polycarboxylate ether superplasticizer is an additive commonly used in concrete engineering and has a wide range of applications. The PCE based admixture can significantly reduce the amount of cement and improve the fluidity and pumpability of concrete while ensuring the strength and durability of concrete.
- Do Polycarboxylate ether/ester superplasticizers affect concrete performance?
- Polycarboxylate ether/ester (PCE) superplasticizers are widely used due to their molecular structural designability, low dosage and high efficiency. However, their high sensitivity and strong interactions with clays in concrete reduce their dispersion and water-reduction capability, which can affect the performance of concrete seriously.
- 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)?
- As one important auxiliary, superplasticizers have attracted lots of attention in the concrete and building materials field. Specially, polycarboxylate superplasticizer (PCE) has been widely applied due to its relatively low doping amount, high water reducing rate and environmental friendliness property.
- What are the advantages of polycarboxylate based superplasticizer?
- Low dosage and high water reduction rate. The water reduction rate of polycarboxylate based superplasticizer can be as high as 45%, which can be used to prepare high-strength and high-performance concrete. Small loss when slump is light.
- How to store PCE polycarboxylate superplasticizer?
- The PCE polycarboxylate superplasticizer should be stored in a cool, dry and well-ventilated place, avoiding direct sunlight and rain. At the same time, it should be kept away from fire and heat sources to prevent fire or explosion accidents. Water seepage problem.
