Polycarboxylate Superplasticizers - Concrete Construction
Some 20 years ago, a new type of superplasticizer based on polycarboxylate polymers (PCE) was commercially introduced to the North American concrete construction industry. Just as the application of naphthalene-based admixtures starting in the 1970s enabled significant improvements in the numerous engineering properties of plastic and hardened

- 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.
- Can hyperbranched solid polycarboxylate superplasticizer be used in cement based grouting?
- The experimental results show that the hyperbranched solid polycarboxylate superplasticizer has a high water-reducing rate and good slump retention. It can be applied in cement-based grouting materials well. Schematic diagram of oxidation-reduction initiation. Comparison of cement slurry fluidity of PCEs. Concrete performance test of PCEs.
- Does polycarboxylate superplasticizer have a good slump retention ability?
- Compared with commercial similar produces and other synthesized slowly-released polycarboxylate superplasticizer, the test results showed that the developed superplasticizer had an excellent slump retention ability. Export citation and abstract BibTeX RIS
- What is a comb-like polycarboxylate superplasticizer (PCE)?
- In this study, a novel comb-like polycarboxylate superplasticizer (PCE) was synthesized using isobutenyl polyethylene glycol (IPEG) and hydroxyethyl acrylate (HEA) by atom transfer radical polymerization (ATRP) (defined as A-CPCE).
- How to synthesis hyperbranched polycarboxylate superplasticizers?
- Here we propose a strategy so called in situ redox polymerization method to synthesis hyperbranched polycarboxylate superplasticizers. By adopting a unique monomer Dimethylaminoethyl Methacrylate, acting as monomer as well as initiator, hyper-branched structure are obtained through this one-pot synthesis procedure.
- How to synthesize a comb-like polycarboxylate superplasticizer with relatively uniform polymer species?
- 1. A comb-like polycarboxylate superplasticizer with relatively uniform polymer species (A-CPCE) was successfully synthesized by ATRP method. Various characterization methods such as 1 H NMR, SEC and SCD determined the acquisition and molecular information of the synthesized products. 2.
