Synthesis and Properties of a Polycarboxylate Superplasticizer with a
Polycarboxylate superplasticizers (PCEs) are comb-shaped polymers with an anionic backbone and several nonionic pendant chains, which typically are comprised of polyethylene glycols. In this study, the synthesis of a new type of superplasticizer is presented, which does not exhibit the typical comb-shaped form of PCEs but is built up from a linear polyetheramine and a hyperbranched
Use of Non-Purified Polycarboxylate Ether (PCE) as Superplasticizer

IOP Conference Series: Earth and Environmental Science PAPER OPEN
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.
Use of Non-Purified Polycarboxylate Ether (PCE) as Superplasticizer
Objective: Aim of this paper is to investigate the interactions between industrial-grade polycarboxylate ether (PCE) polymers and ordinary Portland cement to assess whether is possible to draw structure/performance relations for impure, yet fully characterized, polymers. Method: To this end thirteen PCE polymers were synthesised in industrial fashion, deeply analyzed and tested in cement paste
- What is superplasticizer polycarboxylate?
- Superplasticizer Polycarboxylate Superplasticizer is a new generation superplasticizer based on modified polycarboxylate particularly recommended for ready mixed concrete and civil engineering construction. Its particular configuration allows its delayed adsorption onto the cement particles and disperses them efficiently.
- What is the global Polycarboxylate ether (PCE) superplasticizer market?
- Based on applications, the global polycarboxylate ether (PCE) superplasticizer market is bifurcated into commercial concrete and pre-cast concrete. The commercial concrete segment accounted for market share of 61.2% in 2019.
- What is Polycarboxylate ether superplasticizer?
- These Polycarboxylate Ether Superplasticizer are maintained over extended periods of time compared to conventional plasticizers, such as sulfonated naphthalene/melamine formaldehyde condensates, where flow properties and workability tend to deteriorate significantly over time.
- 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.
- What is Kingsun Polycarboxylate ether superplasticizer?
- Kingsun Polycarboxylate ethers are superplasticizers that have a great strength effect on concrete. They can improve the impermeability, frost resistance, and durability of concrete. Kingsun Polycarboxylate ethers can make concrete have good liquidity and small slump loss at high temperatures.
- What are the advantages of polycarboxylic ether based superplasticizer?
- Polycarboxylic ether based superplasticizers have several advantages compared to other high-range water reducing admixtures. They offer a high water-reduction rate with a small dosage and strong dispersion of cement. Additionally, they provide strong plasticity.
