Progresses in Synthesis of Polycarboxylate Superplasticizer
Through the analysis of references, it was found that PCE synthesized at room temperature had the same performance with PCE synthesized at elevated temperature in terms of conversion rate and...
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 ].

Synthesis and Properties of a Polycarboxylate
Polycarboxylate superplasticizers (PCEs) emerged as one of the most important superplasticizers for concrete due to their superior performance. (1,2) Compared to other products like polycondensates, they fluidize cement even at low water to cement ratios, require relatively low dosages, and exhibit a long slump retention capability. (35) The
A novel shrinkage-reducing polycarboxylate superplasticizer
Synthesis of SR-PCA After getting the AA-C4-PE-600, SR-PCA can be synthesized following the process shown in Fig. 3. Firstly, 50 mL of ultrapure water was put in a four-neck flask with a thermometer, stirrer, dropping funnel and three separated inlets for the reaction solutions.
- How are polycarboxylate superplasticizers synthesized?
- A series of polycarboxylate ratios ratios of different monomers, and adjusted reaction processes. A series of polycarboxylate superplasticizers of different superplasticizers monomers, and (PCEs) (PCEs) was adjusted was synthesized synthesized using reaction using allyl processes.
- 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.

- Does photoinitiated free radical polymerization improve a solid polycarboxylate superplasticizer?
- In our study, a rapid synthesis of a solid polycarboxylate superplasticizer (IPCE10) was achieved using photoinitiated free radical polymerization. IPCE10 exhibited good dispersibility and improved compressive strength in concrete.
- Can comb-like polycarboxylate superplasticizer be synthesized by ATRP method?
- Based on the obtained results, the following conclusions can be drawn: 1. A comb-like polycarboxylate superplasticizer with relatively uniform polymer species (A-CPCE) was successfully synthesized by ATRP method.
- How to synthesize a comb-like polycarboxylate superplasticizer with relatively uniform polymer species?
