Polycarboxylate Superplasticizers - Concrete Construction
Subsequent to the introduction of so-called general purpose PCE superplasticizers, new PCE products have been developed especially designed to provide high early strength and different levels of slump retention, as well as provide different capabilities to manage air contents in concrete.
Effect of Functional Polycarboxylic Acid Superplasticizers on
Modern engineering practices require that polycarboxylic acid high-performance superplasticizers have good adaptability to various environments and materials, which indicates the importance of
Preparation and properties of polycarboxylate superplasticizer
properties of high water holding polycarboxylic acid water redu cer were investigated by using fixed AMEPA dosage as 1.0% of the total amount of DB and Glc, and AME PA dosage as 0.5% o f the total

Concrete Water Reducer - Superplasticizers
7. Since the dosage of polycarboxylic acid superplasticizer is very small, the water reduction rate is high. The use of polycarboxylic acid superplasticizers to prepare various types of high-performance concretes above C45 can greatly reduce project costs and has significant technical and economic benefits; it is used to prepare concrete below C45, although the cost of polycarboxylic acid
- 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.
- Does polycarboxylate superplasticizer alter dispersion and water-reducing effects?
- Polycarboxylate superplasticizer, synthesized using different methods, may alter dispersion and water-reducing effects. The synthesis of PCE involves creating a novel macromolecular monomer with a controllable molecular mass, adjustable lipophilic, and hydrophilic moieties, as outlined in this study.
- What is polycarboxylic ether superplasticizer?
- Introduction Generally, polycarboxylic ether superplasticizer (PCEs) have excellent properties of high water reduction and high slump retention capacity, and they are widely used in engineering , , , . In the synthesis of PCEs, the types of macromonomers are extremely important.
- What is the molecular structure of modified polycarboxylate superplasticizer (PCE-P)?
- The FTIR results revealed that the molecular structure of the modified polycarboxylate superplasticizer (PCE-P) comprised sulfonic acid, carboxylic acid, and polyepoxyethane vinyl groups, exhibiting a comb-like molecular structure.
- Do polycarboxylic superplasticizers increase hydration products?
- The hydration products of C 3 A and C 4 AF in the PC increased with an increase in the dosage of polycarboxylic superplasticizers, and the ζ potential became positive as they become positively charged [76, 77].
