Synthesis and Properties of a Polycarboxylate Superplasticizer with a
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
Synthesis of polycarboxylic ether superplasticizers based on the high
Generally, polycarboxylic ether superplasticizer (PCEs) have excellent properties of high water reduction and high slump retention capacity, and they are widely used in engineering [1], [2], [3], [4]. In the synthesis of PCEs, the types of macromonomers are extremely important.
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
